Not yet. My job seems to has gotten in the way of my hobby. Imagine that.

For the crowd, here's the problem. I've fastened the rear window panels into place thus far using bolts, w/ wingbut on teh inside... drilled holes in the lower corners, upper front area, and at the top overlapping w/ the center roof panel in front. Idea being that I can tighten them down, "pulling" it tight for water sealing (hopefully).
Ran into a problem in the upper rear. The contour of the underside of the roofline (in the ideal location) is not flat, but sloped. Here is a snapshot, circled is where I'd want to drill the hole and have a nut:



b/c of the slope, a nut wouldn't slide onto a bolt if it were poking through there.
I WAS considering instead threading a stud in from above, so that the nut was on the roof. However I'm not sure how/if a stud would stay in place in fiberglass.
Can't use a Nutsert b/c it requires having a flat underside to grip, plus I'd be worried about it cracking the fiberglass when it was crimped into place.

Thoughts?

Corey, I'll get that profile shot you asked for - it requires me taking the top apart again, just haven't had time/daylight.
