While doing some searches on building building up the 12 bolt in my wannabe prerunner 72 Blazer I came accross a link to this outfit. http://www.mitchelldifferential.com/pages/3/index.htm They make a full float kit for 12 bolts. The axles they use are supposed to be 33% stronger than stock. Since Warn isn't making their kit anymore this might be the way to go for those of us that don't want to lose the clearance and lightweight of our 1/2 ton stuff. What do you guys think?
