Hi All - Have a 46' ford Hotrod - half done - I purchased it incomplete - it has a 10 bolt 85 Camaro rearend and a mustang two front end w/ a kit crossmember from about 12 yrs ago - has chev rear calipers and ford front calipers- Rotors are 10-1/2 inches - question is? - where do these calipers come from? - from research I have found that neither the 85 Camaro nor the 74-78 Mustang have this large of rotors. I've heard they could possibly be from a Thunderbird of the same year asa the mustang. - Any help would be greatly appreciated - many thanks in advance - keep "RODDIN" -
