Swapping A/C Set-up to Non-AC Question

[wildmanaaron]

Other than the control panel in the dash, and the actual box on the firewall, what else is different on a Non-AC 73-87 Truck?

I am thinking about removing the A/C set-up on my Blazer since I never drive it with the top on anyways and to get the firewall a little less cluttered. I do plan on keeping all of the A/C set-up if I ever sell the thing though.

What wiring is different? Is there a lot of difference between the box inside the cab different between a Truck that has air and one that doesn't?
