hi all i am new to this site and was just after some help. i have just bought a mk3 gti 16 valve and on closer inspection have noticed the sills have both perished but also the floor on the outside/jacking points. i am not sure if its just me but it looks as if these cars are double skinned on the bottom because te inside floor pan is solid with no rust. my question is, is it possible to get these replacement pans or will i have to form some new pieces with some sheet metal. i have tried everywhere in the uk to get hold of these. any help would be much appreciated. thanks
