Likely a combo of low volume dealer AND , as YOU know, 1996 was a "mixed" model year...Gen I and Gen II motors(cars). I generally like to try to "help" in looking up the parts codes myself when they go to the book or the computer...last time in to check on touch up paint, NONE listed at all for 96 yellow wheels ( I know, I know, some of you think they should have passed on that color in the first place)...LOL
