Bob, even with the stock rear shift location my new cables are 7 feet. I cut off the side to side stud and redrilled it for a 1/4 inch bolt. I used a 1/4 -28 threaded female rod end. I drilled the front to back hole 3/8 and inserted a 3/8 OD, 1/4 ID bronze bushing so that I could use a female rod end on that one too. My plate is on top of the tunnel so I need to shim up the clamps from McMaster for the cables. I'll have photos tomorrow, just started mounting it this afternoon. While I can easily heat the garage a bit to make it livable, my feet get cold and I have to come in to warm them!
I modified the rear brackets and added a bell crank for the twist motion. I mounted that cable to a piece of 2 x 2 aluminum and bolted it with the same holes as the chopped up stock bracket. Photos tomorrow on my thread... ???
