The 8.5 (and the 7.5) seats against a shoulder on the pinion ,and loads the outer race only. The 8.8 Ford has a similar setup.

Years ago I made solid spacers for 12 bolt's and when I was going to put an 8.5 in my HenryJ I looked at making a solid spacer but have it go from bearing to bearing. Went to a 12 bolt instead.
