What's your ceiling look like? I have these rails that run to the rear interior cabin light. They have power, you could try securing it to the ceiling if you have them. Not sure how wise that is, maybe one of the experienced guys can comment on that.

 

I don't have the overhead rail system, so the frustration continues. I am about to sell the darn thing on ebay !!!

 

Take a picture of your cabin.

 

ok, it will take a day or two before I will have the time to get pics taken and posted. Uncle Sam gets plenty of work from me, your taxes are not wasted here.
