T8-MIK-A should be selected if you have:
- 85 or older 4-cyl 3rd member
- 86 or newer 4-cyl with aftermarket R&P
- Inner Pinion Bearing/Race = 32307JR/302307J
T8-MIK-B should be selected if you have:

All of our bearing kits come with either Koyo or Timken bearings, which would be made in Japan or USA. Although Timken does have very few made in other places. Both companies are tier 1 OEM suppliers.
