I spoke to a Cadillac specialist named George today (727) 364-7523. He mostly rebuilds Cadillac steering columns, but has >375,000 parts for GMs from mid-50’s to late 70’s.

As we were talking along he mentioned he may have some of the rare 67-68 4 piston Kelsey Hayes front disc brake rotors.

I’m pretty sure these are very rare, but I don’t need any. I wanted to put a post here in case some of you do need them and do him a good turn since he was very helpful to me on another topic.

I have no idea about pricing, but if you check out his YouTube videos, you’ll get the impression of a guy who does things right, not cheap.

Good luck & good hunting

I'll add that the 67-68 full size rotors for the four piston calipers are not the same as those for the 69-70 single piston calipers. There's a slight difference in the offset from the wheel mounting surface to the friction surface. The single piston sliding calipers are not sensitive to this but the fixed four piston calipers really need the correct rotors. The Camaro rotors can be made to work with the 67-68 calipers, but having OEM is always better.

 

Wow. Amazing find.
