I read somewhere that at some point mother mopar installed
489 gears in some 742 cases on 8 3/4" third members.
it looks like the large 489 pinion bearing works in the 742 outer race. The smaller pinion bearing is different. Does anyone know which small pinion bearing I could use to install 489 gears in my 742 case?
Also are the differential bearing different sizes in both case? Anyone know the part #'s if they are different?
