BUILD THREAD “The Juggernaut”

So it looks like my hand has been forced, y’all are getting an update tonight because I just ran out of MiG wire.
😡😡😡

No offence to you guys, but I’ve been more interested in working on the car than in posting the progress lately. The downside to this however, is that I’m now several weeks behind in bringing y’all back up to speed.
Disclaimer - this might be a multiple post update, lots has transpired since the last, and of course as always, I have tons of pictures to post.

So let’s dive in shall we?

The last Saturday that Mike was over here, I had anticipated making big strides in getting the body mount pedestals welded onto the floor crossmember etc. But as things usually go, that didn’t quite go according to plan. We did accomplish quite a bit that day, but most of it is/was under the car, so no pictures.

Quick recap of what we got done that day, got the transmission crossmember cleaned of all the welding spatter from doing the front floor pieces, and the new upper driveshaft safety loop attached to it. (It fit perfectly, is taller than the old upper loop, and clears the underside of the driveshaft tunnel like it was made for it). Big win there.

We had pulled the trans crossmember to give us better access to be able to hammer and dolly a couple areas in the transmission and driveshaft tunnels, so we spent some time doing that before the crossmember went back in. Another check off the list.

Why did the transmission crossmember have to go back in you ask? Well, long story short, to get the proper driveline angle back. Since we’re messing with exhaust pipes at the rear of the car, any small deviation in the driveline angle up front will have an amplified effect the further back you go.

Once we had the trans crossmember reinstalled and the trans mount snugged down, we reinstalled the rest of the exhaust system again. All this was to confirm and address a wee oversight I had suspected.
Let me explain:

It’s been several years now since when I first fabricated the passenger side exhaust pass-through, and I had obviously forgotten what I had done. The pass-through’s can’t be perfectly straight, the tail pipe portions of the exhaust system have to start curving before they clear the pass-through’s. This means that the front corners of the pass-through’s need to be flared slightly. If they’re not, the 1/2” clearance goes to nil and shjt is gonna hit and rattle.

Again with a long story short, I had done this mod to the passenger side those years back, but had completely forgotten about it before welding in the driver’s side.
Better fix it now.

Cut out/back the offending area, and cut a patch piece out of another section of 4” exhaust tubing:

From a little further back so you can see where this is:

Tacked it in, then reinstalled the tailpipe with my cut down masking tape spacers:

Now the 1/2” of required clearance is back again. Perfect.
Pulled the tailpipe and spacers out again, and burned it in solid.

A little time spent grinding and metal finishing, and it’s like nothing was even done.

To be honest, I was dreading this task, I thought it was going to be a lot harder and more ignorant than it actually was. I got most of it knocked out in an evening, and finished up the details in the next.

Ok, with that corrected, it was finally back to the floor crossmember the following week. I cut out the remaining bit of the original crossmember, and pirated the cage and nut assembly out of it to go in the driver’s side box:

Not going to cover what that entailed, it was literally the exact same as the passenger’s side. Once that was done, it was finally time to unite the new cage boxes with the pedestals.

And after metal finishing them out:

Go time on welding the assemblies to the crossmember! So exciting at this point.

Aaaaand done.

Thinking ahead and starting to get ready to weld the crossmember in permanently, I decided that the ends didn’t have enough surface area to securely spread the load across the car sides. So I whipped up these plates for the ends and welded them to the crossmember:

Yet another test fit, and rewarded with success:

So how is the previous picture any different than all the other ones I’ve posted about the crossmember being in place? This was the first time since cutting the old crossmember out, that I was finally able to fully and properly mount it to the body mounts, bolts and all.
Win!

I thought I was going to be able to get through everything that needed updating in this post, but it’s already way long with a ton of pictures. Think I’m going to call it for now and post another maybe tomorrow night, because there’s still lots to update on. So stay tuned and check back for that!

Thanks for following along if you made it this far guys.

Amazing work as always D!
 
Dude, just build it. Get lost in the process. Enjoy yourself. And update us as time allows.

Oh I have been. Probably more than I’d like to admit. It’s all good though, I really do enjoy the work and figuring out the challenges that present themselves. Now I’m just chomping at the bit to get to a point of having some semblance of a finished product.

What are the odds of a massive burnout occurring with an unfinished car? 🤔

Probably pretty good actually. The Toyo Proxes T1R’s that are on the car are like 98-99% tread, but they’ll be so old and rock hard by the time I’m done that they’ll need replacing anyways.
So might as well sacrifice them to the burnout Gods.

I’m a long ways away from that yet anyways, have way too much to do. Get structure back in the car with the floor sheetmetal, finish the chassis and suspension/steering mods, put the body on a rotisserie and finish the underside, complete the fuel system, complete the air ride system, buy and plumb the hydraulic clutch throw out bearing, clutch pedal, E-brake system, electrical system, custom dash, body mods and the list goes on and on.
 
Going to continue on with the second half of this update, still lots to get y’all current on.

With the successful bolt-in installation of the floor crossmember, I knew I was getting close to being able to start building some floor pans finally. I ponied up and spent a bit of money, bought a new 12” slip roller and a full 4’x8’ sheet of 20 gauge sheetmetal.

Since we’re in full custom territory here, this is the only way to create what I’m going to need. The new rear floors will have to go together as a patchwork quilt of sorts, there’s just going to be way too many odd shapes and contours to create any other way.

It didn’t take long before I started cutting up that virgin piece of sheetmetal, the first thing that had to be done was to make new side panels for the rear firewall. These side pieces will eventually get fully welded in, but up until now I’ve just had them Cleco’d in place. (thankfully)
I had to make new ones because the old ones had already had the bead rolling done to them, and the raised bead roll was going to interfere with the height of the proposed new floor.

So out they came, and new ones were created using the old ones as templates:

Note this tapered flange that sits along the wheelwells, I created this with the new tipping die I picked up for the bead roller a couple months back.

The first time I did this, I didn’t have the bead roller yet, so I had to create them by making a cardboard template of the flanges, then weld them to the sides of the inserts. Doing it with the bead roller not only saved me about 6 hours of labor, but they’ll be much stronger this way as well because it’s still all one piece.

I had every intention of trying to keep the floor crossmember removable for as long as possible, so in these next few pictures it’s still held in with Clecos. Note the ruler looking thing sitting on top of it here, this is a flexible magnetic ruler and has been absolutely indispensable in getting accurate measurements on bent and contoured pieces:

After many many hours of bending, cutting and trimming, I finally had the start of the first section of new rear floor pan!

You can see the level on it, shortly after taking those pictures I used the level to determine where the back of the piece had to meet on the firewall side panel and Cleco’d it in place:

04E2132D-2D7B-41AC-8EBA-2DDDBD8C1B71.jpeg


The floor piece is Cleco’d to the outer face of the firewall panel for now, this is just temporary as I’m going through the mock-up stages. Once the floor piece is ready to get welded in, the flange will be on the backside and invisible. This flange is part of what the side panels will get welded to.

Ok, time to weld it in right? Not even close. There’s currently no structure or strength between the front and rear floors where I cut the old crossmember out from, so one of the first things to do is to create another new floor piece over the driveshaft tunnel to bridge the two sections together again.

Whipped this up on the new slip roller real quick one night, it’ll do the trick nicely:

6CAAFCC4-8E4B-4E31-B3E6-C0BD0D79E774.jpeg


The other thing to do now is to weld the floor crossmember in permanent, no way around that now. So next I Cleco’d it in place for the very last time, and ran the body mount bolts into it from the bottom and snugged it down onto the frame. I got exactly one rosette weld done before I ran out of wire for the night, you can imagine the color of the air when that happened.
But the next day I picked up some new wire and was ready to rock again:

That’s it, the floor crossmember is now a permanent part of the car, it’s never coming out again! We’re pretty much caught up now, I took tonight off, but last night I got the driveshaft tunnel bridge piece clamped and spot welded to the floor crossmember. And a lot tighter with no gaps than the factory ever did.

Going to leave you with one last picture, check out how well and tight these three panels all fit together in this corner. Won’t take much to finesse them together and get them welded out.

I’m off tomorrow for Good Friday, we have family coming for dinner but I should be able to make some pretty good progress during the day before that. The first order of business will be to grind down the rosette welds on the driveshaft tunnel bridge, and then weld it to the front and back parts of the tunnels.

I’ll post up again sometime before the end of the weekend, hopefully I’ll have something substantial to report on again.
Slowly but surely it’s coming together!
Till then gents,

D.
