For the carrier bearing cushion, see the screen shot below grabbed from HERE.

The 1 Ton "cushion" is noted as "3-7/16" OD, where the 3/4 Ton is showing as "3-11/16" OD. Same bearing, but different cushion.

There is an eBay seller (Not Mine) that says they have 3 NORS Doan 2036 cushions available now: https://www.ebay.com/itm/254590428247 (replacement for Cushion, GM# 3657524)

Hope this is helpful??? thumbs_up
