Hello, I am trying to pull out the passanger side kick panel in my 76 nova concours. However, the heater core cover is just in the way enough to prevent the entire A/C housing from being removed. I've been attempting to remove this kick panel so I can repaint it, however it seems just straight out impossible, and even worse, it seems to have a lip on the back side which I have no idea if it will prevent it from being removed. Is there any way to get this out without removing the cover and if I have to remove the cover how difficult is it?
