I've got a 74 blazer w/ 4in (I think) lift and 35 in. bfg a/t's I wan't a reliable daily city driver I rebuilt the 350 and the th350 . My pinion angle is the problem since I've had the truck it's busted u-joints a spider gear blew threw the front of the axle case. the tranny went. I've had half inch spacers put onthe tranny and transfer case and the rears shimmed but now I've gotaleak from the transfer case gasket. should I take it stock?
