1968 Valiant fiberglass doors.

I'm getting ready to start building a two door 1968 Valiant braket car. I'm trying to find two fiberglass doors. Several companies list them. But they are actually Duster doors. The Valiant is a post car and has a frame in circling the window. Is that what everyone is using? I guess just make the lexan window bigger to take up the space for the frame around the window.
I looked when we painted my car and noone made a door with the frame and !I HAD TO HAVE! that 'production' look. I did buy 'glass doors from a local buddy but they needed so much finesse to look 'real' I reasoned it wasn't fair to burn-up my buddy/painters time. I estimated the 2 doors would loose about 85lbs over the gutted and lexan stockers. My 8.50cert car with the cage being moly was 2530 without me. One seat, no chute, !MILD STEEL 2x3! steel floor below driver, 4 link with ARB moly 25.2 tubes in floor, Dana, '440' with 2 4150's, 52lbs 12v battery alternator, rack and C/O front, double beadlock rears. Basically I feel if i tried doing it all over with ladder-bar and round tube back-half and stock floor 8.50 cert and smarter tube routing, I could loose another 60lbs or using only critical tubing. I can loose more than 50 in a smarter electrical system.
