Jaycee - From your picture, it hard to know what part your seeking. Can you provide a picture of the "firewall brake booster" you are describing?

He's looking for the adapter plate that sits on the engine side of the firewall. They make that plate the clear the firewall ribs so they don't get crushed when you sandwich the assembly together. It's the backing plate for the bracket that hangs the pedals/steering column support.
Thanks Mark. That’s what I thought initially, but when I looked at his truck pictures in his Welcome Centre cab Interior picture I saw his pedals in the original under floor location. That and no mention that he was working on converting the brakes was why I asked the question.
