For me, deleting them is a good thing. I think I have only used the rear AC/Heat once in the past 4 years since Ive owned the XK and that was just to see how it worked. Again since I took out the third row seating there is no point in having rear ac/heat. The parts should be in tomorrow id imagine so once they get here ill start working on it. Should only take a few hours to do the swap. Then over to Jays when ever he gets time to do some cutting and welding!
