How to remove Heater Box in 68' Dart WITH factory Air

Hey guys,

I REALLY appreciate all the pics and hints! I managed to get it out yesterday and replace it.

In addition to what you've mentioned, I did have to remove the under dash AC vent assembly along with a bolt on the far left and about halfway up the heater box between the AC assembly and the heater box. It took a bit of maneuvering to get it out, as I tried removing all the clips but it turned out I was missing one.

Thanks again for all the help. The pics and walk-through helped immensely!
