[71 super]

The black were used on the lower option trucks customs and deluxes (the previous statement is a litle misleading as some deluxes had more options than supers for what it is worth). I believe that in late 72 some custom deluxe trucks used the wood trim as well, especially if they were a option code "c" highlander. I bought a bed out of Tenn. that had black lower trim but also had the woodgrained tailgate band. Another wrench in the option set is that some trucks with the tailgate band came with a lower trim piece. The skinny trim "should " not be there but- the 1970 canadian built truck has the tailgate band and the skinny lower tailgate. The truck from tenn had the band with trim under it as well.
