With today's converters (in auto trans applications), I would not ignore putting the braces on both M/T and A/T trans offerings. Some Auto Trans cars leave very hard.

On factory automatic equipped cars, that was only a Chevrolet F41 & Olds 442 deal. In the 90's I used to pull the '68-72 frame braces nearly every month, while out pulling rearend housings, sway bars, etc.. at one time had two 5 gallon buckets full of 68-72 style braces.

Theres a pair of '68-72 braces on my HO auto GT-37, but that's because the original owner bolted them on in the early 70's. He also boxed the upper rear control arms, very similar to what Olds Engrs did for 442's in 66-67 time frame, & he installed boxed lower control arms from a Chevelle.

These braces are always good to add (4-speed or not). I've welded up a few A-body frames that were cracked where the rear cross-member meets the frame. I made my own braces. When I get a chance I'll post pics. I actually have a fixture for making '64-'67 braces.

Any design that will help the rear cross-member and rear axle assembly survive in a good design. Nice Work.

Thanks Tom. It's actually two stainless steel pipe reducers and pipe. I turned the threads out of the reducers. I fitted it all up on the car. Then I made a fixture for both sides off of the prototypes. I had planned to sell these. Never followed through. Lol!
