Correct bearing for Pinion on stock 7.5"

Postby kenimpzoom » Thu Sep 07, 2017 11:49 pm

What is the correct part number for the inner (gear side) bearing for an unmodified case and unmodified pinion on a 76 Chevy Monza with a 7.5"

I have seen some call for a HM88649A and some say HM88649 bearing. Which is correct?

This is what I have so far:
Pinion bearing, gear side HM88649A or HM88649
Pinion bearing race, gear side HM88610
Pinion bearing, yoke side M86649
Pinion bearing race, yoke side M86610
Pinion seal Timken 8610

Thanks, Ken
