Speedway kit for $249, non-power mc from rock auto for $40.00, mc adapter for $89.00. Total of $379.00. I bought my residual valves and proportioning valve from pirate 4x4 for around $30 and the lines and fittings cost me another $50. I have a disc/disc system and had to rebuild the rear calipers, the kits were $7.00 each. So, for complete brake system I'm in around $460. It can be done.
