I finally hooked up the battery and checked all my electrical work. All seems good and there was no smoke.
I also installed a custom driveshaft from Denny's. I needed to figure out a radiator overflow tank and decided to make mirrored tanks on either side of the core support. One is for the radiator overflow and the other is for the windshield washer fluid. I made a simple radius brake for the outer profile and then used my 3D printer to make a hammer form for the ends. It was a fun project and I got a little more experience with aluminum welding. I also made some steel brackets with dimpled corner gussets, again using 3D printed tooling.
