So tonight was a bit of a 'squirrel!' day.

Ran after work trying to find the tap drill for the 5/8-18, a 37/64. Non existent. Nobody stocks anything but 1/16 sized above a 1/2. Great. I've got loads of Morse taper lathe tailstock bits but not a 37/64... I need to see if I can find one from Fastenal or order it if McMaster I guess.

So I got started building a mount so I could put my axle into the lathe carriage and put the drill and tap into the lathe chuck. Then I just need to rotate the axle 72 degrees for each hole and bam, ready to go back in.

Dug through my scrap pile and put something together

Cut some 2" square tube in half

Welded nuts and cut some tabs

Really hot glue gun. Put the mounting bar into the tool post and aligned the V block into a 1" piece of cold rolled.

So now I have a roll cage tubing notcher and a axle pattern redrilling fixture.

But then I thought does the axle fit into the headstock?

Yes. Shoulda checked that first.

And I pulled my live tooling starter kit that I stole from dad who's had it for probably 30 years. Great, this is spiralling out of control...

And I have a headstock indexer, I just need to build an adapter bushing. It's a 40:1 gearbox with anything from a 15 to 40 indexer plate on it so I can go down to .225 degree, 1/1600 of a full rotation resolution.

So, I should just do my best to get the 5/8 studs tapped and 99% chance it will be fine, but I've got all the crap to index the axle and do hole patterns, cut splines, etc., I just have to do the machining to make it work. Once this is done I can pop the axle in and drill and tap with really good accuracy in 10 minutes so....

Follow along on my side quest!

I still was unable to find a 37/64 drill yesterday. I should have just put 1/2-20 studs in and forgot about this mess. I have 2 other options today, I should have just bought one off mcmaster by this point...

I went to plan A and chucked a twisty axle in my lath and drilled and tapped the first hole. I used a 9/16" bit which is 1/64 too small and the tap was pretty tight. So yeah, I need the correct tap drill.

I also got the rear end cover and housing cleaned off of old silicone and re siliconed the UCA plate to the housing.

Drilled & tapped 5/8 holes into my new sacrificial torque twisters

They fit. I wish I would have went 1/2-20 Because I did have to drill these out one size and they're snug to get in, but it's done

But it's done, good to drive for another few weeks.

I think this car is going to the in laws for storage again for the winter and the cutlass is going to get a trans and efi upgrade.

Hey I don't have to like it when it's October!!!

If I had a nickel for every white Halloween as a child or adult. . . October/November are like purgatory, too cold to be summer but too bipolar to commit to being winter.

I ended up ordering the CPP adjustable pro touring style rear swaybar.

Jim got a great deal on his a year ago but the price went up 60% since then. However, it looks like it's the best option for my car as it's one of the few that won't interfere with my fuel system, exhaust, and is something that will be good for both autocross & drag race by adjusting the endlinks. Not aware of anyone else doing that.

I'm sure I'll end up modifying it SOMEHOW but hopefully it will go on pretty easy.
