REAR DISK BRAKES HUMMING

8 3/4 CHRYSLER & DANA 60
This is the sets i used to sell. But were gold car plated back then used some 5x4.5 bolt pattern rotors FORD the inside hubs were opened up to fit over axles hubs. So would fit Mopar axle hubs. You can't just grab the right year FORD ones at Local Auto Parts without machining them to fit. Sounds like a light cut would fix yours. No one here cuts rotors anymore. Just a few large truck places still do.
