Transmission Crossmember Location

[C.I.Blazer]

Trying to think of options for an engine & tranny swap. One of the challenges with my truck is that it is so modified I have no idea what is original and what is not (this is my first Blazer). The truck was originally a 350 with the four speed manual that was swapped for a 400 with TH350 still mated to the (what I assume to be) original NP205. But who knows.

Anyway, can someone tell me if it looks like the transmission is in a stock location? Here are pictures of where the crossmember attaches to the frame on both sides. I measured to the bracket for the body mount just forward of the crossmember. Hope that is clear.

Thanks for the help.

Hmmm. Not sure why the top pic is flipped. The image I loaded has the correct orientation.
