C3 Calipers
I have a 69 roadster, amd need to replace my front calipers.
I have seen listing for version 1 or version 2 calipers. I am looking for calipers that are sleeved, and have o-rings. Is there a difference in how the 2 version fit?
The reason I ask, is that I bought 2 from a local supplier, and both are Delco castings, but the driver's side caliper rubs against the rotor hub(and the brake pad retaining rod). Passenger side has plenty of.clearance. replaced them 8 years ago with lip seal calipers and they were fine.
Is this a tolerance difference, or is there a difference in the version? I thought all C2 & C3 calipers would fit.

The only versions I know of are the '65 & early '66 calipers that have a phenolic disc on the end of the piston and the later-'66 to '82s that do not.
Fitment between them all is the same. Perhaps you have bent mounting ears or the disc isn't fully on the hub.

Does it have 1 bleed screw on the upper end of the caliper?
