Truetrac 8.75, do i need special carrier bearings?

Im getting ready to have my truetrac and gears installed, i need to make sure ive got all the correct parts on hand. This is a 8.75 489 case, 3.91 gears and true trac unit. The rear is currently a 2.76 open. Does this require special size carrier bearings? Does anyone have a link for a good master kit that will work w/the truetrac? I already have a pinion spacer/shims, any help would be greatly appreciated, thanks in advance:burnout:
