Bill,
I can't tell from the photo, but can you fabricate a throttle pedal that could fit on the right side of the steering column?

Doesn't look like there is much you can do with the existing brake and clutch pedals.

If you can't change the location of the throttle pedal, you might want to consider sand casting some new brake & clutch pedals. It's certainly within your skill set.
