Stovebolters - Are the subject running boards interchangable? Why? My '52 'Burb is missing its passenger side running board and could easily be gotten from the same length size from a half ton pick-up. It is the fitment on the rear fender I am unsure of because of 'Burbs having rear fenders skinner than pick-ups. Anyone know? V/r, Nick Cavallaro, Bel Air, MD
