Brent -
The gas pedal om my 37 1/2 ton is a flat pedal that has a pocket made into the bottom on the backside. That bracket on the toe board allows you to slip the pedal onto it and holds it in place. It kind of hinges the pedal. On the top of the pedal on the backside is a round rubberized hole made into the pedal which will accept the ball made on the end of the linkage which comes through the floor board. That spot which accepts the ball is tight and you have to snap the ball into it. Once it is together, it functions very well as the ball in the snap in socket allows the pedal to move as you move it up and down with your foot.
Several of the vendors make the gas pedal and I have even seen New Old Stock ones for sale.
