Backstory: I'm in the market for putting a 3.73 posi, trying to do it cost effective (my truck's not gonna be a high performance road burner, but I still want some get up and go). 2WD's are rare around here, so 3.73 posi's are few and far between for 2WD trucks.
There's a guy locally who's selling a "early 80s" Chevy 12-bolt posi with 4.10's, but its from a K10, so its 6-lug. Would I be able to swap the axles from my 12-bolt into the other 12-bolt? The 12 bolt for sale has also been recently rebuilt, whereas mine is condition unknown (didn't make any funny noises during the 10 miles I put on it before I took it off the road for the engine swap)
Advice?

On your 80 Gmc, you should be able to swap that  The axles should also interchange(just look at the drum widths), & if you find them different, you will need to swap your backing plates also.  Best of fun,crazyL
