Casey,
There is a brake supply business in Santa Rosa, California called Chuck's Brake and Wheel. They seem to have anything related to brakes. They've been in business since 1947. Their phone is 707-542-6012.
Here's some of the stuff they've been able to do or get for me:
Rebuilt my wife's 1960 Mercedes 190SL remote brake booster core and my 1971 Dodge van brake booster core. These cores were in pristine condition and I wanted our own cores back.
Special ordered an antique travel trailer axle to my exact specifications on axle length to +/- 1/16"
Found NOS asbestos friction for various applications. (Like R12 refrigerant asbestos friction is legal to sell if you have it but is no longer manufactured since about 1980)
USA made wheel bearings for various applications rather than junk bearings from China. It's hard to find anything other than China bearings these days.
I wouldn't be surprised if they have the parts you need or can get them within about a day.
