i have a 2003 g35 sport sedan with factory hid xenon low beams. can someone please tell me why im having a hard time finding an aftermarket headlight assembly to replace mine that are damaged from a wreck. they make all kinds of replacements for the coupe with factory hid's, but us sedan owners are out of luck it seems. can a different headlight assembly be hard wired in and get along with the computer system ok??
