hey everyone im back after a couple year break, anyhow i want to install a set of aftermarket roof lights on my 02 2nd Gen. When i pull the headliner down will i find any indication where the holes will need to be drilled in roof (ooch)! almost 100 percent sure the lights are a relica of the o. e. lights, also did the factory be kind enough to run the wiring harness up into the headliner. Last question guys about the screw hardware! nuts or clips? available from the dealer?
