Glass doors will need a lot of work to make presentable and looking stock being that the window glass itself has to be set in the locked position. Many have regretted that decision on a street car.
There's nothing like a stock door on a street car that has been tricked out. Only you know the secrets. People can call out a fiberglass door from a mile away. On a race car I can see the reasoning, but on a street/strip combo, steel in any gauge is the way to go.
Those Dusters have been down to 2900 Lbs with all steel parts for the most part.
