Just like third gens, any of them could have had a posi however most lockers will be a gov loc. The only way to find out is to spin the wheels if the cars are supported, checking for a G80 RPO code or pulling rear covers. When spinning wheels, if one goes forward and the other backward, it's not a posi.

also check out the cutlass and the blazers (80's). but you have to crack them open or jack them up to see if they are really posi.

just avoid the LS1 (more power and abuse) and not all 80's were 7.5, the Grand National and 442 have a different rear even though it's a ten bolt (still grab it though whole thing is worth 1K)

Huh? I would much rather have a LS1 rear that can be 6-10 years old with a zexel carrier and 28 spline axles and 12 inch disks with aluminum calipers. than a 30 year old G-body rear.

to each there own I guess
