Am I correct that the sunvisors for my Dec 55 Kabriolet should be this shape:

These have a square shaped edge rather than the curved edges I see on other Kabriolets (Such as Martin's 55).

I now have all the parts to make up my rear view mirror assembly - does anyone know of a source for the plastic in the visors or know of anyone who can vacuum form the lip in them please?
Many thanks,
Dave
