1971 Jimmy trans swap time

[Treachera]

Hi, thanks for the info. The guy I bought it from said 302..as for engine identification, I have no idea how to tell a 302 from a 305. for the TC, I was planning on swapping the frame cross member too.. I noticed they were a little different. Seems like the cross member on the newer truck wraps up and around the frame, where as the '71's cross-members bolts to the insides..I could be wrong though.. I'll throw some pics up when I get home.
