35-36 rear trans mount. Source for rubber ring?

[rehpotsirhcj]

I‘m putting together a parts list for a toploader rebuild, my winter project. I have the 48-5089 rear mount which is clean and ready to go, but the rubber was hashed.
Replacements include both the steel mount and the rubber bushing, but the gauge looks thinner, and it’s $50 when I only need $10 worth of rubber to go with my better quality stock mount.

Anyone have a source a part no. for just the rubber or the best quality of full replacement?

Thanks much,
-Chris
