David, the reason I didn't go with the power booster as bad as I wanted to was twofold... Brothers tech told me that I would have two problems.. 1) With a 3 speed w/overdrive, the linkages would be in the way, and 2) The original transmission crossmember would have to be cut out a bit to accommodate the booster. I noticed you have a 4 speed with torque tube rearend, so you wouldn't have these problems. My plan is to go without the booster to see how manageable the disc brakes are without it first. Thanks for the pics!
Deve, I have a regular 3 on the tree transmission, no OD. So, I sure hope the linkages work out ok with no interference...haven't got to that point yet, but have to assume this would be the most common setup to design the system to fit/work with. I did have to modify the original cross member, by creating a few notches so that the MC cleared. To avoid cutting too deeply into the cross member, I made a series of "step" notches, then boxed them out. I relocated the proportioning valve to the frame as can be seen.
