Those things look nice! Only 31 pounds savings? I would think the hood alone would be more than that, over steel. And the cowl hood is just a nice design, no matter if it's a "GM" thing. I think they look good on cars, and would especially on your Maverick.
I'd also be on the fence about painting them. Kind of like aluminum heads; you want to show them off, but hiding them in factory color is pretty cool also.
