First off, its a Shell Valley 91' build, the motor head rebuilding the car says he think their off of a late 80's mustang, fairline, or maybe a Lincoln. I have had no luck finding matching calipers in junk yards or the internet. The bracket you see on the rear end does not line up with the caliper and fabbing a bracket that goes over the disc (which we don't have either) would be near impossible without knowing how big a disc and what the offset is. The numbers on the caliper are as follows:
US Patents
No 4,261,466
No 4,499,977
Made in
Australia
K241-1220

I am not in front of the calipers at this time but this is what I can get from the pic and I how what I am reading is right..

Please help because we are ready to break this motor in and get this thing flying down the road.. Thanks for any help guys.
