There is a solution - Jeff Bloom from Aust Muscle Car Traders is making these for Mk 2 2 Doors.
How do I know this? Jeff bought some old doors cards from me and was going to use these to build moulds for after market reproductions. I've sent him an email after this post ewent up to see how it was progressing. He has come back to me and tells me they are available for $880 (4 door cards) plus $55 freight Aust wide. I haven't seen pic, but he indicated they have the chrome Mylar (?) - it appears the Aldridge ones don't have this (only based on their web site).
Owners of 4 Doors - I've sent an email back to see if he is making these so I'll update this post when I get a reply.
