Your link and drawings are very helpful. I was thinking of installing the channel bar just in front of the raised area you talked of. The need to raise the rear of the non-original tracks led me to the idea of a channel bar(for neatness) this would allow me to weld in studs for the belt mounts and the track rear mounts. Doing this all out of the truck and then mount the bar to the truck. Solve two problems at once. I do see there is some planning needed here. The dimentions in the drawing will be helpful. Tom
