1970 Duster project in Sweden
I fabbed one using fiberglass, resin, a homemade buck and an old cotton Tee shirt. I used a peel film on the buck to be able to seperate it. I brushed on 5 layers of resin on the stretched cotton tee shirt. Scuffing between layers of resin as I built it up. This made it stiff enough to pop it from the mould. I screwed it down upside down to plywood, then I wet layed up 2 layers of 7781 fiberglass and resin. 3 layers at the proposed attach points. Then I cut it out and sanded it down. I added reinforcements with JB weld at the top and bottom. Made brackets out of 22 gage steel sheet. These I glued on with JB weld, and used aluminum solid rivets on the fingers. I set it in place and marked where I had to drill the mounting holes. I sprayed it with a few coats of sandable lacquer primer.
