So I'm in the middle of my 4.0 swap in my 1990 b2, it has a chop top and will mostly be used for trail running. Ive been thinking about gutting the A/C system, but not sure if I want to. It's never had A/C so I don't think I would miss it. But it might be nice for the AZ summers. I don't know how good it would work with no top anyway. Is there a way to get rid of the A/C and keep the heater?
