John,
I may have a 27 headlight trim ring. I will have to see what kind of shape it's in. They can be carefully straightened and polished up nice. I have the 28 rings and got one of mine to turn out good, but the other I think I will need to replace. Gary Wallace has the lenses and gaskets in reproduction. If I recall the lenses are $25 each and the gasket set is $15.
I have no hardware for the upper windshield.
I was going to private message you on the other items and for pictures, but I guess I am not a high enough level member to do that (so it told me anyway) so if you want to send me your email maybe you can PM me?
I will get a picture of the trim piece for the seam. It is basically a rolled sheet metal 'C' channel with screw holes in it.
