I have great success with u tube videos for most tasks but this time I relied on a kid that I'm convinced has never done this. Per his instructions I have removed the dashboard and still can't find how to "just pull the heater core right out and change it.
I am looking at the complete air handler box complete with a fan on the right a box in the center with the A/C coil and a box on the left that has the heater coil behind it showing partially. I removed the intake manifold and removed the hoses. I also have to return the heater coil because it is the wrong shape(straight tubes, not turned 90 degrees. The one I found online only fits a 300M. The birthday on my Sebring is February 1999.
How can I get the black air handler box to open and release the heater core?
I appreciate your help.

I have attached an image. Remove lap cooler duct installation screw and center duct. Remove semi-rear A/C duct and foot distribution duct. Remove clip. Slide heater unit back. Remove heater unit and heater core.

I am past all the plastic air distribution ducts. I have removed all the screws and nuts from the black air system. Will the whole thing come away from the inside of the firewall? I can shake it all back and forth but it won't come out very much. The hose connections are about four or five inches long and pointing forward. That seems a long way to move the whole system. Will the evaporator coil move at the same time?
There are three black boxes hooked together and I can't see how to separate them or pull them away from the wall. Am I missing something?
Are there any bolts holding the system from the engine compartment?

It should pull out, but I cant say for sure. The information I provided is all I can find in my software. Only way I could say for sure is if I was there to look at it.

Well I appreciate that but I need more help.
Is there a mechanic that has familiarity with this exact car?
I have seen the diagrams but this device is complicated and as of yet I have not actually broken anything. The black box on the left(where the heater core is) shares a lower mounting tab with the center box(where the evaporator core is and I don't want to move that too much as it works well) but the center mount was installed after the left side(the center tab is covering the left box tab). It feels strange to keep pulling all of it out just to free the left box.
I know this car was made a long time ago and actually in Illinois by Mitsubishi. I was told 2 car has some possibly retired mechanics so I am counting on an older pro that has worked on this car and is still living.

I just wanted to say, all I could do would be to look at our site database and post removal procedure. If that will help, I can post it. I've changed many heater cores but not every year--make--model. Otherwise, I'm just like Johnny, I'd have to look at it.
