Get a picture of how the linkage from the pedals hooks up to the tranny. Maybe someone will have a suggestion.
I'm not familiar with that model, but if the linkage moves a lever on a shaft at the tranny end, you might be able to reverse the lever on the shaft so that it reverses the effect of the forward and reverse pedals.
