Hi Bill, for some reason 1970 (not sure about 1969) is rare. They were a two piece 12" rotor. I cant seem to find them. Also the Disc spindle is different than the drum brake set up. So far all I can locate that will fit is 11" Corvette discs and Wilwood makes an aftermarket set up. I do not even know if there are original reman OE rotors available. If anybody has an interchange manual or a source for the original set up I am all ears. I will get serious on my research after I get the AC and the exhaust installed. If I am stuck with having to go with a not original set up, I will probably do the 4 wheel disc Corvette set up. I figure the slight benefit of the rear disc setup might offset the extra heat that the smaller 11" rotors will generate in the front compared to the OE 12" rotors.Disc Brakes were an option in '69, maybe even standard on some models. The '69 and '70 had the same 1-Piston Caliper Brakes. You may want to try to find an original set.
