Drilled some holes on the bracket, and was able to use a hole already in the rear of the frame. Same hole I used to run a ground wire from the tail light housing.
Road legal again:
That should get me by until the new bumper gets here
Also poured new oil into the engine, transmission, and rear diff. Reg. oil with Zinc additive for the engine, Redline MT-90 for the transmission, and Redline 75w-90 synthetic GL5 for the rear diff.
