#90 BULB LED REPLACEMENT

Has anyone found an LED replacement bulb for the courtesy lights in the rear interior panels? I'm working on a 68 Dart convertible and I'm replacing all the interior lights with LED. The stock bulb # is 90 for the rear courtesy lights. I'm running into a problem finding a bulb that will work.

Problem #1. Most of the replacement #90 LED bulbs I'm finding use the bulbs "case/base" for a ground. Both of the contacts on the bottom of these bulbs are +. The bulbs need to be +- on the contacts to work in this application.

Problem #2. You are limited to a really short bulb since the bulb has to fit inside the glass "dome" that clips into the rear interior panels. I bought some bulbs that are the correct +- on the contacts but they are too tall to fit inside the dome.(they are 1/4" too tall)

If I can't find a bulb that fits, I thought about trying to make a spacer to fit on the back side of the glass dome...to space the taller bulb out so it will work.
