    Hey guys!

    I'd like to convert my 1972 Challenger Rallye 340 4-speed car from 4 wheel drum brakes, to front disc brakes. I need to know what I need to make this conversion? Do I need a new Master Cylinder? Do I need a new Proportioning Valve? New backing plates?

    I am not necessarily looking for upgraded brakes, I'm actually looking go with the smallest disc brake setup possible, as I'd like to run 14" or maybe even 13" wheels.

    Please list anything I would need to make this happen, and make it happen ASAP.

    Thanks Guys!!!

    Talk to Cass at Doctor Diff, He uses off the self parts, and the price is good. The linked parts kit below has most the available options that you might need, but still call him to see if he recommends anything else to complete the job.

    why would you want to fit 13 inch wheels? 14 inch were the smallest they came with.
