cheers lads, yeah I love the shell, if I was given the choice of any car in the world it would be an audi S1, thanks nosmonkey, oddly enough the teeth on the diff cases are fine on this but the 2 centre gears are too far gone to use again, the belts will probably be fine but if I can get some new ones I'd be happier, I'm after an original red air filter that would have been on when new as I'm trying to keep it original, if anybody has any spares or knows where I can get these bits I'd be really grateful, I've marked on the pic in yellow where the gears go that i need, I'm wondering if these were used on any other cars at all cos then I could widen my search a bit, thanks again everbody
