quick question. are the 71-72 front brake rotors the only ones with the wear line etched in the rotor? or did the 73 and up ones come that way as well?

i've never seen them past 72, replacements won't have the grove. that was to tell you when they needed replacing.

thats what I figured the groove was for. I just picked one up at a yard for 7 dollars with lots of meat left on it. I just wanted to make sure it didnt come off the 77 1/2 ton sitting next to it

.
It was tossed in the back of a 71 along with the hub assy and control arms and calipers.
