Hi Dave,
Got your email but will reply here as others may be interested at some point in the future!
On mine, the roller had already beem replaced with a normal pedal. However it was not a very sophisticated upgrade! Basically someone had got a random accelerator pedal (very similar to the one I have on my MG) and then welded a chuck of 'U Channel' to the back of the pedal and then drilled through and bolted through the hole where the roller previously was.The bolt squeezed the U channel sufficiently to stop it waggling back and forth. I then drilled the old pedal to mount the new aluminum pedal to.
If I was doing it from scratch, I'd probably just get a suitable sized chunk of 'U channel' and bolt the ally pedal directly to that, then on to the pedal arm. If you chose a deeper piece of U Channel you could put through a secondary bolt behind the pedal arm to stop any other movement.
Hope that makes sense?
Cheers
Phil
