I have a 1965 Chevy step-side. The side inner fenders each have a metal 'L' shaped strip to hold the wood flooring into place that are welded/rusted to the fenders. Mine are too rotted to salvage. Which leaves me with 3 questions. 1. Do I just grind them off? 2. Does anyone make replacements? 3. If not, any tips on fabricating new ones? Thanks! Janine
