Rear interior sail panel lamps. January 14, 2020, 02:32:34 PM Anybody have a part number for the rear interior light housings on the sail panels, specifically the 87-88s? Probably something along the lines of "XXXX-13776-a".Reason I ask is that the it appears that the trim surround and wiring on these didn't really change much over a 30 year span and the biggest change seems to be the type of bulb used. This may open up a lot of possibilities. Looks like some of the older late 60s-early 70s models use a type 89 bulb or equivalent. That'd probably be one you'd wanna use an LED in place of an incandescent.
