Front Suspension Upgrade

'64 Barracuda, Gen 3 Hemi, Tremec 6sp, 8.75 rear. Doing the torsion bar delete, converting to coil-overs, Mustang II spindles, rack & pinion steering. Question: What brake rotor/caliper works on those spindles. The OE Mustang/Pinto are 9.25" OD, even the ones with 5x4.5 BC.
