I have a Brand new, never out of the box, RPM Engineering disc brake conversion kit. It may fit other years.
Complete Power Disc Kit includes: Rotors, calipers, bearings, seals, hardware, booster, master cylinder, mounting brackets, valves, brake lines, and fittings. 5X5 bolt pattern, I think.$1400 and I'll pay the shipping in the U.S. They were $1595 plus shipping when I bought them. No, I won't negotiate!
