Sorry, guess I should have clarified that install 2 different units in 2 different vehicle's other than X frame cars. But both units had defrost builtin to them.
I'm curious about these units as well. Anybody install one on a factory air car? Even after the sun goes down it's 90+ degrees. Never thought i'd consider it but I miss driving the ol girl.
I have the "Sure Fit Gen IV" in my factory air car.
Polly is STILL at the interior shop, though, so I don't have any experience with the performance of the air conditioning in the ample Impala cabin. This pict shows the unit in the cabin below the dash. Makes for a clean engine compartment
