I just went out and snapped this pic for you... it isn't very good but maybe gives you an idea. I have mine to where the brake and clutch pedal sit at pretty much the same height, not sure if it is supposed to be that way or not. The angle is hard to see but I would guess the top of the pedal is about 1.5" from the pedal stop. I did see Shafi's post that it should be all the way up to the stop, but mine seems to be working fine as-is and I have the proper travel at the master cylinder.

I need to clean it up a bit under there, maybe I can get the car out in the driveway tomorrow for a better pic, I took this laying across the seat and console and upside down.

Again this is a 69 Coronet so your E-Body might be different.
