So what is up with my crossmember? I took a turbo 350 out of my truck when I first got it.. dont ask any questions about it I have no clue what year or what it came out of..

So I ripped that P.O.S. out and replaced it with a brand new rebuilt turbo 350.. and dont ask about this one either.. got it cheap from a buddy and rebuilt it.. with a badass shift kit and a reverse manual valve body and when I drop it in and try to line up the new tranny mount to the old tranny cross member its not even close.. HELP!! That 30lb sledge in the corner is looking like a pretty good option..

Thanks alot everyone.. Bo

Crossmember upside down or something,or one of those trannies is a 400.

possibly a different tail length? I don't know if that changes the crossmember location or not. Trucks came with the 6" tail. TH350's came in 6, 9 and 12" lengths.

I put a 700R4 in my truck and I had to move my crossmember back....I just unbolted it, slid it back, and drilled new holes....I mounted the tailshaft to the x-member and then took measurements for squareness before I drilled...good luck!
