The 8 1/4 thread

so basically i bought that carrier/pinion ring gear setup. the carrier bearings that came with the new carrier were to big outside diameter but inside diameter was the same size as the ones on the old carrier and pinion bearing was the same inside and outside diameter but got new bearing as well.

So i bought new factory type/size bearings for the old carrier and installed them on the new carrier and did new axle seals and bearings as well.
