hello! I am trying to change the heater core on my 70 coupe with air what a pain by the way. ok i have most of the dash out all loose but not all the way out. i hope i can get it this way i have it pulled away on passanger side. so i see the one bolt on the top inside and a few on the outside to get the box loose is that what i need to do is pull the box out of the car or do i leave the box bolted in an take off the bottom of the heater box?
thank you Tom

That is the expansion valve, the little line is the temp sensor line.

The bulb is the reader. It is a pressure switch. It is what make the A/C work.
