When keeping the underfloor brake location on a 55 f100 but converting to automac tran. what type of pin or bolt system can be used when doing away with the clutch to hold the brake peddle in place and not binding?

 

On my 52 I got rid of the clutch pedal.My son was in high school at the time and he machined me up a nice new pin that fit just the brake pedal back in..

 

Drive the roll pin out, remove the clutch pedal, cut off the arm leaving just the round area where the roll pin goes. You'll never see it when installed but you could dress it up and shape it with a grinder and sander. Stick it back on the shaft and install the roll pin.

 

I used a bolt with a nylock nut
