WHY does Car-Parts.com not list Dodge Ram 50s, but instead lists only D50s? So they have listings for -- such like -- 1990 and 1992 D50s which, if I understand correctly, didn't exist in '90 ... or '92 (and I have the listing right here in front of my beady little eyes).

Am I wrong, or are they just clearly inaccurate ... or weird? / Christopher
