I have two rear brake drums from a 77 Matador wagon I will be putting on Ebay if no one wants them here. 10 inches by 2.5 inches. I think these are the biggest drums that AMC cars ever used. $15 apiece plus shipping from CA. They are used but they appear to be good. I will measure to make sure they are not oversize before sale.
