Like you I insist on being able to heel 'n toe, even on my old working HiLux. On my current Plus Four I have actually shaped a piece of half inch plywood and screwed it to the accelerator to raise the level slightly. It works a treat and is in keeping with the use of wood in the frame. So, don't be afraid to mess around with bending pedals or adding height to the accelerator etc to get just the right setup.
