Best source for fiberglass?

[Gellpak]

I'm planning to put the gt front apron on my '66, but I've been told that the quality of these can vary widely from manufacturer to manufacturer... does anyone have the same part on their car, was it much trouble to install? Who did you buy it from?

I have installed a few fiberglass parts. I have worked with maier racing and fiberglass specialists pieces. Both of which I had no problem with. Any fiberglass piece requires some work for a good fit.
