Yes. I went to the dealer and told them I needed all the heater/AC lines for a Commander without the 3rd row seating (no rear ac/heat).
At this point you need need to delete them. Trust me. A friends boss has the same XK as mine and her rear lines were leaking. Talk about a pain in the butt to replace. We had to totally unbolt the rear subframe that the rear track bar is bolted to so we could get the lines ran above it where they belong. Parts were over $300 for those lines plus you need to recharge the AC again. Just delete them bro and save yourself the hassle.
