i posted a question in that forum also but ill put it in here 2 just in case those are cool looking im gonna do that pretty soon but what i really want and i cant find right now is the other over head light in the headliner. i have a ext cab silverado and it is the light in the middle of the front seat and the rear seats. i have been to a few places with no luck. the bulb is a small cylinder size shaped bulb, probably about 1" to 1"1/2 maybe not that big at all. any info on that? in the owners manual they dont give the bulb type of # in there and says to contact local dealership but i hate dealing with the one here in town they are not to good at customer service.....thanks again for any info.....TrEy:D
