Overall Assessment

Our product is distinguished for its confirmed quality and usability mainly for full-size Chevrolet vehicles. It effectively performs its function, with no reported issues. However, customers noted it's incompatible with a 1964 Pontiac Catalina due to the sizing of the steering bracket holes. It instantly sets itself apart for Chevrolet users, offering superior functionality and fit when compared to others in the market.

I already have installed a disc break conversion kit on my 66 Parisienne, that came with 11.5" rotors. Will these spindles work with that size of rotor? I have 15" wheels on the fronts.
