OEM Rear Brake Disc O.D.?

davidnunnMember

Does anyone here have an OEM, '71 to '74 unmodified rear brake rotor they could measure for me? I need to know the correct O.D. I've been able to find the spec. in a number of different places, including here, but there isn't a clear consensus. The closest seems to be 11.7" but different sources cite different dimensions. Thanks!

I've got a 72 and 73. The 72 is 11 3/8".

I've got an entire set in very good condition if they are needed. I switched to WW. Thanks.
