@pizzaman09 Black was available all years, 86-89 is called Classic Black (PX6 vs. PX8 for 90-92). When you filter select the “contains” option and enter black.
I never did try it on my taillights, but here’s an update on the headlights, lasted about two years before they were cloudy enough to bother me. Not as bad as in the picture two years ago but enough for me to redo it today.
