I picked mine up today and it is a nice looking piece. I ended up running my new 2/0 cable under the car again. I also installed a new 2/0 ground from the engine up front to the frame rail and another 2/0 ground from the battery to the frame in the rear. I also reused my old 2ga cable as a ground from the bell housing in the front to the battery negative in the trunk. New contactors and plungers in the mini starter too. Starter turns over without any drag now. Real test will be tomorrow when I take it out and see how it starts when heat soaked.

Looks like I may have it ready for the track next weekend after all.
