I purchased a front disc brake set up from a used parts supplier I was told it was off a 71 or 72 Chevelle, this set up had 11" rotors is this correct ?
Thanks Rich02

Can't say offhand. I could measure for you this evening when I get home, however. I just put the second rotor on last night. I haven't finished with the caliper yet, so it's still hangin' out there waiting for the finish-up.

My '70 has original factory 11" rotors.

Billscamino, thanks for that info, it helps confirm what I have and thanks TH.
