Just finished my '69 Camaro conversion. NPD has a kit that has EVERYTHING needed in it to do the job, does not inc. the master cylinder/booster or prop valve. My brakes work great, I did not replace my prop valve or m/c, I have no booster.
Street Bandit Disc Brakes is what they call the kits.
67-69 Standard spindles $449.95 C-5800P-1A (NPD part number)
67-69 2" drop spindles $539.95 C-5800P-2A
Booster/Master cylinder kit $249.95 C-4901P-21A
No, I don't work for them. I actually think they sort of suck, but that is the best deal I have seen on brake conversions. Good luck, let us know how it works out. That is my car in the picture.
Man, I got to damn much time on my hands!!
