I have a Swiss Champion numbered for a while, however to register the car in my country I have to pay something like 9000€ and pay a road tax of 500€ annually due to the cc and co2 of the engine.

Switzerland is non Euro zone , so different rules apply

The car is from Switzerland where they all came originally.

I bough a shell from a 92 valver (phase 1) the Swiss Champion is a phase 2 (1995 car).

My intention is to paint the valver shell 432 blue and transfer everything from the Swiss Champion to the valver (engine, gearbox, ECU, suspension, interior etc.

Does anyone know if is there any difference in terms off wiring from a valver to a Williams?

The valver doesn't have electric rear view mirrors and the SC has.

I want to rescue the car because it's the rarest of the Williams but paying a fortune is just out of the question.

If someone could help me
