I need a rearend

[bglad420]

OK heres the deal. I have a 70 GMC LWB Fleet, witha BB402. The main bearings or oil pump started to give (oil pressure dropped unless it was gassed at 3000 rpm) so I parked waiting on $$ for a rebuild. So while the truck sat I had a 78 GMC Jimmy with a fresh 375 Horse 327, and a Turbo 350 set up for a drag car (I was working at a tranny shop, and the guy that owned it decided to build me the most retarded trans chirped my 33's in all three gears) Well I was going through a rearend, a week, and u joints like crazy. Long story short I ran out of rearend parts so I gutted the trucks rearend and well now I have no rearend for my truck and I need one BAD! preferably with 3.73 So if someone can help me out. Thanks!
