Here it is mounted. Only 2 bolts are holding it in right here, up against the front bulkhead. The bolts run through the flat areas right next to where the vertical bulkhead meets the angled underdash area. Should be a very strong point, and the forces are spread through the bolts AND by the bracket just butting up against the bulkhead.
I did just a little more grinding on the pedal frame so it would fit up snug against the steering column
Here are the two bolts. Sorry they are too long, but I had planned on a thicker backing plate that I ended up not really needing. I'll get the correct length ones later.
