76 Duster A/C removal

if you're removing your a/c, i assume it's a weight savings thing...my advice: just take out what's left of the a/c and remove the heater box (that thing weighs a ton) and don't even run a heater....all you have to do is join the lines that would usually run to the heater core and that's it! That would be the lightest setup, cleans up the engine bay, and looks factory inside the car...
