Trade 40-series Early windshield frame for 63-64-65 corrugated top frame

I been collecting parts for some time for a corrugated top `65 build. It just dawned on me today that I have the wrong windshield frame. The good news is it's a very early rust free frame. I have the vent knob and misc. parts, the vent operates freely. I'm in the need of a similar frame but with the clamp down brackets on the side. I believe these changed from this style in `62, to the clamp style which is what I need in `63. I'd be willing to trade up for a solid frame in good condition. Or do you have what I need? I might just have to sell this, and buy what I need. Thanks for looking..
