Dana 30

Does anybody know which bearings Come stock on the early 90's Dana 30 ring and pinion front differential, Koyo or timken?

Doesn't matter since Koyo and Timken are owned by the same company now.

Reason I was asking is because I purchased a Dana 30 with 3:54 gears I'm swapping into a Cherokee. I was removing the pinion to instal new bearings and noticed the outer pinion bearing was a Timken, the inner bearing a NTN and the carrier bearings were Koyo's.
This thing has probably been disassembled twice before.
