best 5x4.5 disc conversion on my 1968 dart 2dr post

Dr Diff has everything from Stock 10.95" Single piston calipers to multi piston Brembo 13" rotor kits. Cass is awesome too.

Agree. I sourced my front disc conversion from a 77 Volare wagon and then used adapter parts from Dr. Diff. Cass was very helpful and responded to questions right away. I'm also running an 8.8 out of a 97 Explorer, 4:10 gears, posi and disc brakes.
