I did some more cross referencing, and found some more part numbers:

14"x2.5" Front Brake Shoes - $65 for a set for 4
Normal - Raybestos 109RR
Premium - Raybestos 109PG

I guess there was also an option for larger 15x3 brakes. I do not have these on my C50.

15"x3" Front Brake Shoes
Normal - Raybestos 134PG
Premium - Raybestos 134RR

Still no luck on the rear shoes, but luckily my rear shoes are still in good shape.

Worst case, I could probably reline them myself like I did with the parking brake, but I am not sure I trust my own work that much... yet. smile

No information on front or rear drums yet, but they are pretty beefy and should be able to be machined again if needed.
