Hi, I and several others have used Dave Ross body shop and painting to replace rear wheel arches and sill on both Mk1 & Mk2's to great effect. To my knowledge he has done several Tayside members cars plus others from further afield. His contact Number is - 07752 960994
Paul Mitchell (North Isla Street Paint shop ) also uses Dave on occasions for welding work too as he now mainly concentrates on panel spraying to all manor of vehicles and caravans. very good too !!
Recommend both of them.
