Mine had a perfect set of Aluminum doors , but I really didn't like the looks, so I intended to make my own,, but insted , like a fool I sold them, and ended up having to buy glass ones,, the only fiberglass on the car,, but they are a very nice pair,, made by Pro Laminates over in your part of the world,, keep up the nice work,, youre making great progress,, wish I could say the same about mine,, got way too many irons in the fire,,
