I hope I am not high-jacking this thread, but I pulled a drum off of the back of my 64 dart, 8 3/4 10" x ?, because it locks up when I step on the brakes, and noticed that there is a good 1/4 inch of more of unused drum on one side of the shoe. The shoe measures less than 2", so I am assuming someone, not me, put the wrong shoes on it. The question is do I need 2 1/4 or 2 1/2 shoes ? or do I need to measure the drum better? I know I need a different proportioning valve, that is a different subject.
Thanks
PS. dual master, front disks from a 69 and all small pattern.
