Coolcruiser,
I cant believe what you are starting with; it kind of makes me quesy looking at it all twisted like that!
But I dare say that your windshield frame is NOT going to hammer out. I am nearing the end of my 45 build (or at least to the point that I know I dont need this any more), and I happen to have a windshield frame for a removable top to spare. It has the capture nut holes for the hooks the top latches too. I bought the whole windshield because I needed the impossible to find hook/latches. Looks like you have those in the mangled remains of your roof and windshield.
If you are interested, drop me a PM and we will work something out. I head over to the LA area from time to time and would be happy to arrange to meet to save shipping and all of that hassle (besides, doesnt look like you need it real soon).
Also, its odd that the remaining bottom portion of the windshield doesnt have the vent in it (mine does; I thought all mid-sixties did).
Looking forward to watching you build that back up. Please post lots of photos.
