Posi is it worth it?
I found this ad for a posi unit it looks a little worn but for the price is it worth it to pick this up? Would this work for a non posi 1970 Gmc? http://phoenix.craigslist.org/evl/pts/3894175069.html

Re: Posi is it worth it?
Me personally? I wouldn't buy a 40 year old unrebuilt posi-traction unit. When for $150 more you can have a brand new Eaton unit.
