New to me 1962 GMC B4000

[RSMCCRAW]

Hey everyone!
I picked up a B4000 the other day for 500 bucks.
I was wondering if anyone had any parts numbers or sources of information that I'm needing.

Mainly I need a Brake Master Cylinder. It has vacuum assisted power brakes.
Also the brake booster that sits underneath the cab would be great to have a replacement if the master cylinder isn't the only thing wrong with it.

Does anyone have any other brake shoe part numbers or anything else I might be able to use to source brake parts? Im having a lot of trouble finding part numbers or anywhere to purchase parts for this thing.

It runs great, it has the 305 v6 in it and it starts up on first bump.

Here are some pictures.



My first priority is going to be replacing the wheels. These are definitly the RH5's and I dont even like them sitting in my yard with pressure.

Thanks for looking everyone, I look forward to hanging out here.
