A few of us have been around since these cars were brand new. Front clips interchange and were dirt cheap then. Unless you class raced[most didn't] aluminum fronts were so dent prone, some traded them for steel. We knew factory workers back then but when you ask them what color crayon they used to OK stuff they[and rightly so] said "who cares...we were either drunk or irritated at the company". Makes documentation even more of a guess than.......These cars are big fun and "special info" will always be debated.
