The '68 I was thinking about is actually a '67 (silly me), but I also have the '68 from Tim in Bristol. Might be up for sale again soon - I've decided that I maybe should have a clear out. Doesn't have the beige dash. The '67 car has a beige dash, but I've decided I like it now.
You are welcome to poke around my window frames. I've decided not to use any of the metal ones - too much hassle for me.
