I have a hole in my headliner between the T-tops. There is a threaded metal sleeve under the hole. Is this just for a retainer to help hold up the headliner, or am I missing an overhead light. The car in the front seat floor area is pretty dark at night, but there is an overhead light nearby in the back seat area by the hatch back. The only lighting in the front comes from the bottom of the mirror. I have never had a T-top car before. If anyone can solve the riddle thanks in advance.

 

There is no light between the T-tops Just at the rear hatch and the rear-view mirror.

 

Yip, even my hard top only has the mirror and rear hatch light.
