Is it possible for me to find a sunroof and headliner from a LS in a junkyard, and install it on my truck? i know i wouldent be able to mess up cutting the hole, but is there something different about the roof of a ls? now for wiring it, isnt it true that most base models are kinda wired to install higher model stuff? or would i have to figure out all the wiring for myself? after seeing a ls and its huge sunroof, i must have one
