Hello, and thanks for the responses. Again, I have a 3/4 ton truck and the drums with studs and nuts. I am not planning on changing them out. The drums I purchased with the parts lot, I agree, will be for a 1/2 ton truck and it makes sense that this is the drum difference between them. Digging through the catalogs I feel the shoes, wheel cylinders and miscellaneous other parts should work on my truck as they are the same part numbers for both the 1/2 and 3/4 ton units. I feel like I still came out ahead as I can sell the 1/2 ton drums. I also have a set of drums from the rear end of a Chrysler, approximately 1948 if anyone's interested? Los Control, am I wrong in thinking I've seen trucks running 11" drums in the rear and 10" in the front?
Again, thanks much for the help.
John
