Hi guys, I am in the process of buying a 79 GMC one ton for parts. It has a dana 60 front, 14 bolt SRW rear. I looked at the xfer case, and it looks like a 203, not a 205 like I would expect. Shouldn't it have a 205? How can I id the tranny? I think it's a TH400, kind of looks like Illinois, right? But TH350s look like a square with one corner cut off, right? Thanks very much for your help.
