Hey everyone. Since my car is going into the shop next week to get my 350 installed. I was thinking of getting the guy to weld a bar in to tie my rear frame rails together. What's the best way to do this? I don't care about extra weight (the more weight on the rear the better in my opinion lol). So if any of you have pics of yours, could you post them on here? thanks in advance.
my project Caballero has the rear rail tied with a light duty hitch made of square tubing. I'm not a fan of how mine was done but it does serve its purpose. The thing I don't like about it was the tubing was welded along the bottom of the frame and it looks home built. Its mounted right at the rear of the gas tank about 6'' from the end I'm contemplating cutting the hitch off though.
Its not real pretty to look at that's why I have no pictures of it. Seen a similar looking one on another thread here though just recently.
The easiest thing to do is use some 1x steel tubing, drill a couple of holes and mount it using the same bolts used to bolt your bumper shocks to the frame.
There's really not a lot of room back there to weld a piece in without hitting the fuel tank, spare tire wheel well, etc.

Yeah, that's how my Bonneville was done. Didn't really like how that looked either.

does an additional rear xmember really make any difference? the bumper seems to do the same job as the fabrication? I'm not being a smart *ss either. A drag racing guy I know chopped his rear frame and put light duty tubing frame in its place. He said "all it does is hold your bumper anyway"

I used to think the same thing about the rear bumper. But then someone pointed out to me that the bumper does little to nothing because of the bumper shocks.
So with that, there is nothing solid between the rear frame rails from the rear axle to the back. So it;s kind of like a nig tuning fork. I hear a lot of the vibrations and rattles these cars have can be eliminated with that. That's why I'm slowly trying to get every factory g-body brace these cars had. After this, all I have left are the cowl to rad support, trunk x-braces, and the frame mounts.
It actually helps quite a bit with the overal ride and rigidity feeling of the car.
Keep in mind drag racers don't really care about what the car does outside of a 1/4 mile so they tend to eliminate things that for most road going cars improve their ride, handling and overall comfort. The rear brace helps more on a road car that sees curves, bumps, etc.
fair enough, i can buy the rigidity argument, you guys might try el camino bumper shocks then, they are non-functional solid mount, which may further stiffen things!
anyone who has done a frame off has seen the independent movement of the rear rails. Even with a boxed frame with upgrading the factory weld the rear rails still move around. I use one of those hidden hitches to tie the two rails together and upgraded the bolt sizes to 7/16" for the bolt at the end of the bumper shock (I just tapped the anchor mounted on the end of the shock) and used 3"8 bolts to install the flange of the bumper shock assembly.
