D56-57:Pedal Mounting D1/2

I spent the last couple of days working on the pedal assembly and getting the factory pedals mounted in the frame. The first change needed was angling the mount about 15 degrees to replicate the factory mounting of the brake booster and master cylinder. In the first two pics are the modifications made to the frame to achieve this angle.

The next step was integrating the original mounting plates into the new firewall. Below is the firewall from the BMW that will be used instead of recreating it in new sheet metal. The original plan was to make the new firewall a single piece. After mocking everything up, it was obvious that another solution would be needed.

The new solution is a 2 piece solution. The top half of the firewall to mount the pedal assembly and then add the bottom half as a separate piece. Below is the top half with original firewall wall piece and the new firewall separate...

...and then on top of each other which will be the final assembly. Reusing the original means I don't need to go out an buy all the necessary hole saws to replicate the original. I'm trying to keep this as low cost as possible.
