....if I remember correctly Jackyl converted a 1952 one ton to a 1/2 ton. If thats the case the hole for the m/c were probably different than my 52panel. I used m/c-booster from PirateJack out of Asheville, N.C. and it was a direct bolt in. All the stuff I needed at a good price and I didn't have to drill one hole. I did have to cut the brake pedal hole out about 1/4' at the top....and as I said above I had to modify my crossmember but maybe that was just because of the crossmember itself and not because of the choice of systems?
Jackyl, be sure and bench bleed the m/c real good because sometimes they can be a pain to get all the air out!
