Stevan,
I have a set of brakes that would meet your '70 to '71 description. One thing I noticed on this set's caliper arms are the words "BREV INTER." are missing the first period after BREV. On all later arms I see "BREV. INTER." Of course this could have been a mistake in the stamping or tooling but both arms are the same. Has anyone else noticed this?
