Heater core....

I got the dash out now. How many screws are holding the heater case to the firewall in the inside of the car? I got the one that is just above the carpet. In the engine compartment, the heater hose clamps are loosened up and the nuts of the bolts holding the evaporator case to the firewall are off. I got the two screws holding the cover off the heater case off but can't reach the other two because I can't pull it out anymore.
Alright, I got the two nuts off of each side of the accumulator. The black nut (in the second picture) is loosened up so it can come off. But the line is still connected, how does it come off? It looks like some kind of connector, but it doesn't turn or anything. Any ideas on how to disconnect the bottom line that goes from the accumulator into the firewall?
^Thanks man. I don't think I will want to do this again, (although I probably will because I like the foxes. LOL) It wasn't too bad, if I got hung up on something my Dad would help me out. The only problems I had was disconnecting those connectors that ford used for their electrical, and getting the heater core out away from the firewall enough to take the screws out of the top of the heater case. Other than that, it was a good learning experience, I've never done anything that drastic before. 
Well I tried to start the car and see if the heat works and the gauges work.... it didn't start. The battery has some juice, but I will put it on the charger tomorrow. The gauges are all hooked up, the hvac is hooked up, the airbag power supply is connected. The things that aren't connected is the fog lights, headlights, emergency lights, defroster switch, cd player, cigarette lighter, parking brake connector, that's it. Is there anything built into the car that would prevent it from starting if something was unplugged? There is some kind of car alarm on it, but everything seems to be hooked up with that also. It's a 1990, I didn't think they would put anything as far as fail safe things in it but I have no idea. All the lines for the heater core and accumulator are hooked up too. I really don't see anything else that could prevent it from starting, the car doesn't even try to roll over at all. Like I said I'll put the battery on the charger longer tomorrow to see if it's the battery but I'm looking for some suggestions as to why it won't start.
It's a stick, when I try to start it I can hear some kind of clicking in the engine compartment on the drivers side. The lights, cd player, and gauges work. I don't think I unplugged anything on the steering column, nothing needed to be unplugged for any reason, I did drop the whole thing down though to take out the dash cluster.
