It's kind of a mish-mash of folded over pieces, but like Justin said, it could probably still be fixed with single sheet metal bits.
But there is a top kit ("kit" being the bad word here) that might include that. I don't have a picture, but search Dynacorn and hard top and see what you can come up with.
The parts that I remember are the top panel itself, the inside braces, and the outer rim.
Whether the rim includes just the drip rail, or includes the wider windshield section you're hunting for I do not know.
Good luck.
