I think a 3/4" offset linkage rod inside the cab with a one ton modern hydroboost would work well. The pedal doesn't need much pressure with the boost. But I'm going to stick with a rebuilt factory setup for now. BTW does anybody know how much torque to use on the four J bolts that hold the hydrovac tank together? The rubber O ring is so thin I'm afraid of ruining it. The one that was in it was so tight it disappeared completely but that doesn't seem right to me
