Any Ford nine inch gurus on here. I need some identification assistance. I have an unknown sourced Ford nine inch rear end under my Studebaker pick up. It has disc brakes and looks to have had coil springs before it was adapted to leaf set up. One of my calipers is leaking fluid. Where should I look for numbers to either ID the source car and year, or on the caliper to get a part number. Quick look says the caliper is likely an aftermarket caliper not a genuine fomoco item.
