Cool, thanks for the pics. I think I have the proper gas pedal that would allow me to use that instead but wanted to see yours also. I also like the shift mounted one and thought it might look hinkey but yours looks pretty clean. But if I go to the gas pedal a dash version would probably be the straightest shot. Thanks again for the pictures, that makes a lot of sense. Not so worried about the deadman feature as pushing the clutch pretty much takes a running engine out of the equation.
I think the oem-type connection to the pedal has to be somewhat cumbersome - it's not a natural movement - like having the hand throttle on the gear shift...
If you have the appropriate gas pedal, you only need to go from the gear shift to the pedal - you may need to fab a bracket to allow the cable to maintain the proper approach. But, I think that would be easily done.
Just be sure you test it out and make sure your foot overrides the hand throttle and that the hand throttle doesn't interfere...
I don't know how @Fast Eddy hooked his up (pedal or bellcrank), but I know @sggoat hooked his to the pedal - maybe he will chime in to answer any pedal-related questions.
