What do you mean work around?  Those systems are intended for cars that didn't have any of the duct work needed for air conditioning.  Are you saying your car doesn't have any vents in the dash?

As stated, those systems are typically for cars that don't have factory AC already there. I had one in a 61 Chrysler Newport, it was in there when I bought it so I didn't have to figure out brackets for the compressor or where to drill holes in the firewall for the lines along with condenser placement and all that fun stuff. It worked great but if you already have AC, it might cost more to fix but should be much easier to actually fix instead of doing an install of a (cheaper) universal system.

With the plastic dashes of the '70's, if you fit an under-dash unit, you might have to reinforce the mounting points to stop the dash from collapsing.

I would be recommending fixing the original system, as it is far superior to the simple under-dash aftermarket systems.

They may be complex, but they are fully Air Conditioning both Cold and Hot.
