I have been trying for a while to find out whether the parts for the rear drums on the Maverick (the 77) were the same as the 10" Mustang drum parts. I suspected so, but haven't been able to confirm it. I discovered today that Autozone lists these parts on their website, and they do have the same part numbers. I was looking for the self-adjuster repair kit. One other thing that I found was that they show the same part number for the self-adjust lever itself between the 9" and 10" Maverick drums, which is different from what I was told by someone at a Ford dealership who checked their microfiche for old part #'s. I'll be picking up the self-adjuster repair kits after work for only 6.39 each!
