Thanks for the input, I will be leaving them off in the restoration. By the way, miraculously this 76 Z has no rust not even under the rocker panels... it was Ziebart treated and outside only for nice weather.... paint is just weather beaten. And the carpeting is no good... even the floors have original paint.
