Denny,you're wide awake and it sounds like Bradw1876 is talking about the propshaft center support bearing. The 88107 part number is available as you've shown at most local auto parts stores, NAPA, Autozone, etc.
I chose to use NOS parts. I read in the shop manual that replacing the cushion (3657524) was not dictated but I fail to see how you could reuse one.Mine was destroyed when the bearing seized so it wasn't even a consideration. They are very hard to find these days.
I also trashed the shield (3705198) getting it off, so I replaced it.
When I got to the cushion /bearing the shims were worn down to almost nothing and I ended up replacing both shims (2019793) and both retainers (3685957).
By the way, Denny, your photo album was extremely helpful when I did this repair, thanks for taking the time to make it available.
It took some time to locate all of the repair parts but its back to original, for what's its worth. I hope that Bradw1876 has less to replace on his repair.
Note, after I got about half way through this adventure it was suggested by another Bolter that I go get a modern "carrier" bearing and make a "riser" to get the right distance from the frame. That's what Chev's of the 40's has in its kit along with a shield. In hindsight, that may have been the easiest approach....but not original. Perhaps I'm both Crazy and Dusty.
