we have confirmed the ones with the bumps on the top are for all 65 and 66 shelbys but what are these other drums from?? the one with the bumps on top is date coded and the other one is not..both are marked KH E 50430 Jimmy
Hi Jimmy, I still have the original brake drums on my 66 GT350 and they are like your second picture, they do not have the three small bumps. One has a cast date code of 2-1-66 and the other is 2-3-66. The KH numbers are the same as yours. Dave
