Im doing a 700r4 tranny swap in my 69 camaro with a 2000 crate motor 350/330hp and putting in a 700r4. Ordered a crossmember from chevy bowtie in ca. And dont fit.same thing when i got a crossmember from summit racing, same problem, looks like whole engine and tranny need to come back about 2-4 inches for mount to fit. Holes on frame dont line up either. Anyone have this trouble or any suggestions, help please

My crossmember is a modified Th-400 crossmember. I have heard the easiest swap is to use your original crossmember and slide it back a couple of inches in the sub-frame. Then drill new holes in the sub-frame to mount it. Usually there are 3-holes on each side of your sub-frame. Make sure you are not trying to use the forward holes. You may have to use the rearward holes and drill the farthest back holes.

or torch cut old th350 crossmember to access bolts like my mechanic did.

Heres one that should work but not cheap.
