8 3/4 question..please advise

I would prefer seeing you using a 489 or 742 case,with that kind of power..the 741 has the weakest pinion bearing of the 8 3/4's...my duster with the 416 stroker making only 520 h.p.,snapped the driverside wheel studs clean off one day,then ripped the driveshaft right off the pinion yoke another, taking no more chances,i installed a set of Moser axles w/1/2" studs,and billet yoke,had a custom 3"driveshaft made with the 1350 yokes,and of coarse i'm running a 489 case,the last thing i'm worried about is my rear,your getting up there in power and the stock stuff CAN'T handle it,i found that out..8)
