65 the good bad and ugly

Original kickdown and throttle cables will not work. He has a Holley Street Dominator, not an OEM intake. The MOPAR arm is for the Edelbrock Carb, not the intake. If the suspension seems tight, double check everything, then look at tires and alignment. Not an OEM alignment but a High Performance alignment. There are quite a few threads here about alignment. As for disc brakes, I'd go with OEM Kelsey-Hays or an aftermarket if you want to keep the original small bolt pattern wheels. There should be factory service manuals on line, I have original paper ones.
