I looked on the Internet on Advance Auto for the b body and they are all 11" drums. I've got drums for a 73 duster 10"x 2 1/2 coming and will try those tomorrow. The 10" drums in that era fit 74,75, etc...Dusters and Darts as well as the trucks. They have the same part number. The Yukon axles stick out 3/8 more than the stock axles so that might help with the 1 3/4 shoes I have or might not fit at all. I'm not getting my hopes up.
I really would dislike have to take everything back loose and convert to the "big" brakes. I will do anything to avoid that if I can truly help it. I might just have to get my drums machined to 2 3/4 center.
