JL8 front calipers on my car?

[92646]

Ok my car is weird and it keeps getting weirder all the time. The car is an LA built car and it was built in November of 1968 so it is to early to be a JL8 car. The car had 15 inch rally wheels on it when I bought it and I have 14 inch steel XT style wheels on it now and I have not measured the rotors yet. The car has no other sign of it being a JL8 other than the front calipers. Was there another caliper out there that would look the same as one of these calipers that would work in a stock application? I am about ready to change them to the regular single puck caliper to clear my wheels if this is the case or is there something else out there that I am not aware of and I should leave it alone?
