I have have plenty of Tach tape for the flywheel so that will not be a problem. The torpedo is wide enough that is for sure but I am not sure about the length. I had taken the shell off the torpedo and there is not much under the shell at all. If I can fit it lengthwise than I can use the existing mounting brackets but would most like have to tap a couple of holes for screws which is no problem. I can extend any wires as that is what I had to do for my last transplant and it worked fine. I know people say the 5 V boards fail often but knock on wood none of mine have yet and I have a lot of them. The last time I did this I just unscrewed everything and left it intact and after the install I just had to extend the wires.
