From 1960 till 1970 ALL front AND rear brake shoes were !1" X 2", front and rear!!! Half ton stuff.

Half tone rear brake shoes, 71, 72, 73 (yes 73 being first year of square bodies!) were all 11" X 2" shoes.

74 and up, half tons could have either 11" X 2" rear shoes, or 11-5/32" X 2-3/4" shoes, this went all the way to 1987.

all half ton info, here...
