Does anyone know where to get rear arches from? Put my finger through them this morning .

I think Fluffy had some, but no longer.

Small sections can be fabricated and welded in (please but them, no plating!) but it requires a good quality MIG (the metal is very thin) or TIG.

You might find some decent ones on a scrap car -- I'm pretty sure that Sei and Cinq inners are identical (the outers are different).

Or you night be able to adapt some from a car with better panel availability.

Thanks, I will just have to make some I think
