If I was you and insisted on running a 8 3/4 third member instead of a Dana 60 I would look for and buy a 742 case and add a steel cap with studs on the drivers side up twocents


I ran a stock 742 forever as you know Cab and these new nodular units are better than the all mighty 742.......... biggrin beer


Do they have more pinion support than stock cases?
