  13. Interior Door Card

    Hi folks. I need to replace the material part insert on my passenger door. I've sourced a replacement which is better than mine which has a small rip in it. My question is whether I can take the whole inner door card off without first taking off the outer door skin/panel? Any advice appreciated

  17. Size of torx screws in upper rear light?

    Hi all - silly question probably, but does anyone know what the size of the torx screws in the upper rear brake light on the roadster is? I went to a shop yesterday and guessed 20 ... I was wrong! So I'd like to know for sure when I go back and try to change it.
