Thanks, Dan beat me to it.

I'd also suggest drilling the hole in the brake pedal for the pushrod just a bit higher than FFR suggests. I'd drill two, one where FFR suggests and another just high enough above it that there is enough metal between the two holes. Once the pedal is in the car with the dash and everything else in place, it's a SERIOUS pain in the butt to take the pedal cluster all the way out, disassemble it, and drill the second hole (if you decide you want more leverage). You will need to disassemble the pedal cluster to drill that second hole, BTW, since the bracket gets in your way. Just tap the spring pins out with a roll pin punch and the whole thing comes apart.
