360 Roller Build - Advice, etc. (Lengthy)

You want weight reduction?!?!?!
Hot Rod magazine did a Duster with just that single goal in mind. The link I do not have handy but it has been posted here several times. Besides the basic fiberglass everything, they also did Lexan windows, aluminum center section on the rear, tube K frame and attaching parts. Do a search here or at Hot Rod for it and see what weight reduction is really about.

that Duster bracket races here in Vegas....
