Phat Boy:
Try Pickups North West, as far as I know they are the only ones who make a unit that will work with a standard trans. Master Power makes excellent conversions, and their quality of customer support is also excellent. I blieve that the MP units are designed for auto trans equipped vehicles but check with Carmen or Anwar at MP they really know their brakes. Also let whoever you're dealing with know if your truck is Drum-Drum, Disc-Drum, or Disc-Disc as each configuration may require a different master cylinder and/or proprtioning valve!!! For my 52 3/4 ton I used the Pickups NW conversion, on my other vehicles I've used the MP conversions.
