Greetings. I purchased a '72 Mav (wreck), for the rear end to install into my 1967 Mustang. The old rear brake drums are 10" x 1-3/4" with a 2-3/4" center hole. However I am having difficulty finding replacement drums with a 2-3/4" center hole, they all seem to have a 2-1/2" center hole. The rear end Identification tag reads WDW-AA 7CB 2 79 8 536A. I have since determined that this is probably from a 1975 or newer car. Any thoughts and assistance would be greatly appreciated. Also, would the backing plate accept 2" brake shoes?
