Are these cars all fiberglass ? Just wandering because a buddy of mine has a demon & its all steel ( fenders, doors, trunk lid, quarters, roof ) fiberglass hood. It has all the glass & window cranks. small block He only got to run a few times last year & it ran the best of 8.85 in the 1/4 In the next couple of years he wants to do all fiberglass & a twin turbo.
