i searched around and only could come up with stuff from like 2004 that were in a archive. i have a 2003 cavalier and i was thinking of swapping out the interior except for the back quaters to a 2003 up sunfire interior . is theyr someone whos done this that can help me out and tell me what im gonna have to get in order to do it. i read something about the HVAC , would i have to change that too . if so why?
thanx

Im doing the conversion right now. I dont think you need to swap the hvac controlls (I hope not) byt you do need the vents
