I have been working on a 66 chevy c60 2 ton dump truck. Found the parts and got the brakes working. It took some time to find the numbers,and it was a bit frustrating. I posted the part numbers in the swap meet section under parts for sale. I do not sell them, but did not want to post them in the wrong place and have them removed. And I wanted to share them in the hopes it will make someone esles job a bit easier, in the future.
