So far everything Ive done mechanically ive found from Napa. They probably wont be able to look anything up by application, but as long as you have a part number, weather it be a GM number or other manufacturer, they can usually find it.
The parts that you are looking for fit a variety of different trucks right up through the 70's & 80's.

Check for any numbers on your master cylinder. I was able to come up with a master cylinder by the numbers on mine. mine had a Wagner lockheed number on it, and is still available.

With a little digging, I was able to find all the wheel cylinders. the brake hoses, the master cylinder,& all the bearings in the 2 spd rear end.

If you need a hand with part numbers, I have a couple of old GM parts catalogs that cover our trucks.


Do you still have those numbers? I have a 1946 3 ton that needs a complete brake job. And new bearings in the rear end couldn't hurt
