Dave, nice deal with getting your son to make the grade.
Well nice thing about fiberglass you can cut and mold with out a set of tourches. We have a member that put a 63 splitwindow on his C3. That will make you look twice. So it should not look to much different than a convertable. Search out How to make my C3 a convertable and see what comes up.
Sure sounds like a project......so how do the other grades fit in this time?
Good luck, keep us posted.............and welcome to the site
