What is the part number for them, I can't find it. I had it wrote down from when I put them on my 94 that I sold. Thanks

Just go to a parts store and ask for GM rear wheel cylinders for a one ton 94. A good parts guy will find it.

 

You will find your info here

I did a search for you. Here is the best info I could find: Napa #4637337
Don't tell the Napa guys what the part is or what it's going on, it will just confuse them and you won't get the right part.
Just the above part number is enough. You can even order online by going to www.napaonline.com
The info is courtesy of infidel.
