After a lot of head scratching, and a lot of fab work, plus some modifications, I finally got the gilmer belt system mocked up. Definitely not a bolt in thing, and luckily I had a $5 swap meet alternator bracket that I reworked to fit.
Then I punched a bunch of holes in the axle with a holesaw and lots of Rapid Tap. Got all 11 drilled with one bit!!!!
Finally cleaned up the front floor pans and painted them too. So shiny the camera didn't want to focus, or it was high on fumes!
