hi ive got a 1981 sl, i took it into my mates for a long awaited respray when he took the left side headlight out there wasnt much left behind but a bag of rust , the question is do i need a whole new wing as it all seems to be part of the same or as he asked is there a kind of bucket part(plastic?) that sits behind the light as the rest of the wing is sound... hope you understand what im on about..... thanks
