if you KNOW it is good, and you don't know how or at least know someone to help you set one up then you did alright I suppose.You sure can't build one for .that
I bought one used rearend way back and I got my rearend used on that deal. I thought a fire truck was chasing me it howled so bad..lol
and then it turned out what I thought was a "12 bolt" was one of them goofy OLdsmobile rearends that had 12 bolts in the cover but had an oddball 10 bolt carier in it. :cry:
