I talked to Rick again today and he said he was initially going to get the side moldings until the dealer said they only came with a black insert. So he declined. The dealer then said they could install a white set...by drilling holes and screwing them onto the car. Rick then said no way.
As for the stripes, Rick doesn't know why they didn't show up on the car or why he didn't raise a stink about it when it arrived without them.
BTW, here's an article from the 1988 HPP with a white-on-white SD Formula with the stripes...and white dealer installed side moldings!
And what's really funny is that I have a photo of this exact car that I took at the Musclecar Nationals in 1986!
