Ihave had the wing dowel thing happen to me on another model. All Idid was wrap the dowels with light fiberglass cloth and soak them with thin CA. Then Isanded them to fit. If you have severe dents, wrap that area first with strands of the glass, CA, sand flush, then do what Imentioned previously.
As far as the windshield, That price is absolutely insane! Ihave made tons of windshields over the years. Check this link and do it the old fashion way.

Just make a paper template, cut it out and you will be all set. Tower used to carry the stuff. Get the large sheets.
Ihope this helps.
