Yes, there is a bell crank. I just realized it does the same thing (reduce pedal travel and leverage) as a lower hole on the pedal. But I can see why lowering the hole would not be a good way to go.

Also, looking under the dash I can feel there are some threads exposed on the pushrod, which means I should be able to shorten it. However, I suspect the under-dash return spring would still want to pull the pedal all the way back up against the rubber stop. I'll have to play with that. I may have to look into welding a steel pad onto the pedal arm, and/or using a thicker rubber stop.

I'll be pulling the instrument panel this fall to rewire the truck, and will probably pull the seat, too, which should give me better access to all things under the dash. I'll pull the steering column if necessary, but it's a PITA to reconnect it to the intermediate shaft.
