Do all MPi cars have that extended bit on it or is that only a Cooper or Sportpack thing? I bought an MPIi shell to replaced the rolled one in my 95 (slim pickings over here in the US) and it came with the extended throttle pedal. Seems like it would be decent to drive with.
I ma going to say that just about every pedal fitted to a Mini will fit as my 94 was fitted at JCG with a alloy throttle pedal. It was not just a pedal cover (like their brake and clutch covers) but a pre-1976 throttle assembly (tiny little pedal) and the alloy bit bolted to that. The same goes for the Paddy Hopkirt and Speedwell covers as they are all meant to be fitted to a pre-1976 pedal assemblies.
