express van 2500 rear any good?

[dragn91]

I'm doing a 6 lug conversion on my c20 I bought some spindles and front brakes off this van I'm going to try to run I noticed it has a pretty beefy looking 6 lug rear in it as well. I can prolly pick it up for 100-150 bucks. Are these rears any good I can get a free 6 lug rear from a 95 ish truck but it looks pretty wimpy or a squarebody 12 bolt for 50 bucks. Anyone know what rears they put in those 2500 express vans it's around a 1999 or 2000
