For those that have fabricated their own trans crossmember to put a T56 in an older car (first gen Camaro for me), what size tubing (OD and wall thickness) did you use? I'm thinking I will use 2" angle for the mount to the subframe, then a 2" tube bent between them and a 1/4" plate for the trans mount. Just trying to decide what thickness I want to use for the tubing....

Wow, 1 1/4" huh? I thought my idea of 2" was on the low side. I've seen some pretty beefy ones from the aftermarket, but the stock one isn't much. I was thinking about an 1/8" wall too. Thanks for the feedback. Free is always good!!

Yeah I'm gonna try bending the pipe as close to the floor pan as possible to make clearance for the exhaust (probably not 3" tho LOL). Thanks! We'll see how good my bending skills are. If not good, I'll be shelling out a few hundy on an aftermarket one. Thanks!

For my 71' Nova, I didn't make mine from scratch. i used a TH400 and cut it up.. I used some 1/4" plate steel and a 2x4 tube to complete the cross tube for the Trans Mount.
Not a T56, but the idea should work for one.

Thanks! Good to know I can go smaller diameter than I planned. Will enable more clearance. Steel shop was closed yesterday, so I won't be able to start on this today like I hoped. I thought about modifying the stock crossmember similar to what you did, BC. Nice and clean. I want to try tubing first though to try getting as much exhaust clearance as possible. I'll post what I come up with.

1 1/2 .250 wall square tube for the trans mount. Then i took 1" heavy wall square tubing and tied the trans brace into the rear leaf spring perch on the frame to help with frame twist. Overkill for the trans but it didn't hurt the chassis strength lol.

I took my Yank 4l80 Crossmember from my Camaro and chopped it up to use it for my mount...
stuck with square tubing since it was already using square tubing on the one from Yank.
I used some scraps that were laying around from another project...
its all thick wall tubing, couldnt tell you anything other than that.
This is the Yank Crossmember
This is what I ended up with for my Foxbody
