I used the Tilton pedal set-up. The master cylinders fit fine. I used 3/4 MC's for the brakes & a 7/8 for the clutch. I used a Lokar "spoon" gas pedal, with Lokar cable.
I did use a "Chevy starter heat shield" from Speedway motors, over the brake line, closest to the headers. It's chrome or stainless & works well.
I did a "mod" to the front leg of the "bridge" or body support. We cut "notches" in it, so it could be shaped, & re-welded, to make more foot room. It is "tight", for your left foot, no matter what.
