Problems with my 700R4 has forced me to switch to a built turbo 400. I need a stock crossmember to complete the swap. Moved to Sparks, NV from So Cal 2 mos ago and junkyards here are no help. 68-72 should work, 70-72 for sure. Any truth to rumors that turbo 350 and 400 crossmembers are different? Thanks guys! paintgod77

I have a big block crossmember but I'm not 100% sure if its for a th350 or 400... The bolt holes look close to the th350 tranny mounts I just replaced (small block crossmember) But I haven't measured. I just moved to the Ranchos (S. of Carson) so I'm fairly close...
