In the middle of a thoroughbred project with the engine apart and am hunting for a very early NOS HP 289 clutch pressure plate with light green springs. Part number C3OZ-7563-A. These were sold individually or part of a Cobra clutch kit with the clutch disc. I do have several equally cool nos parts for 65-66 that ai could trade if needed (including NOS Cobra engine dress up kit with nos HP distributor, cap, plug wires and Cobra medallions. One of several I could offer for part trade).
