hey guys, thanks for any responses. I have a 74 Roadrunner that I am attempting to swap the rear drum brakes for disc. It has a 8.75 rear from a 64 Imperial. As far as I can tell the rear lug pattern is either 5 x 5.5 or 5 x 5.25. Anyway, my question is, will any rear conversion kit fit as long as it's for a 8.75 rear, or will I have to find one that matches the rear from the imperial precisely.
