Good 4.5" b/c convertion site
I don't any specific sites other than the one 69signetv8, came up with, but here is a pic of a wilwood disc brake kit that converts to the 4.5 bolt pattern made for A body Mopars with 10 inch drum spindles. The pic compares a 9 inch drum to the 11 inch wilwood rotor. For the rear you can put a 8 1/4 rear from a later model A body with the 4.5 BC. For cheap front disc's pull them from any later A body with 4.5 BC Disc's. My pick and pull let me take every thing I needed for my buddy's 68 valiant for $80.00, and they came off 74 Duster.
