A/C Heater Box rebuild

[Pentastar Pete]

I have a 74 Challenger A/C - Heater box. I want to restore the box while my dash is out. Does anyone have an exploded view of these A/C Boxes??
I have taken 1 or 2 apart in the past and never could get the doors right...
Thanks

I can`t really help but is it together now ? if so take pix as you disassemble it

I did my AC box and it was pretty easy. I did have plenty of pics though. Heres an illustration from the parts catalog. Also, let mne know if you need actuators; I havea full set and other leftovers 

[Pentastar Pete]

I will take plenty of pic's along the way. 
 The illustration does help.
Thanks

actually, that image was shrunk for other illustrative purposes. The pic was taken from the parts manual and I can get you the full page shot which should show you most everything

[Pentastar Pete]

Ok, thank You

Can I get a pic too... I have my out of the car and ready to be rebuilt but I am afraid I will screw something up. It looks pretty good on the outside but I am scared of those doors too! PLEASE DO A WRITEUP ON THIS... so I dont screw mine up! HA!

2challengers2 - Where are you getting your Evaporator core from? I have only found them on ebay and they are like $225.00. The heater core is also like $80.00....

Can I get mine rebuilt if they are decent?

Hey mike
I might be interested in the actuators if 2challengers2 doesn't need them. I'm about to take mine apart, it's a mess.

[miketyler]

Sure, no problem. He hasnt said anything so they are available to anyone.

Actually I have a long list of parts that I need to add to my "Tylers Leftovers" ad. I should update that list today

I just went thur a rebuild with my heater box.  The A/C core was tested with a tub of water and compressed air.  No leaks.  The heater core was a different story.  I was able to get one from AutoZone for about $54.00.  It is the same one from year one for about $80.00.  I have a section on the box in my site labeled  "Repairing Heater Box" ...July 2006.  Site is   http://big-dog.us/challenger/   Good luck. David   PS. You can tell that my box must have been jammed into the firewall at one time since several spots were broken.............

[EvilTwinATX]

can you post the part number of the heater core from autozone?

Mike, Thanks for the diagram.  I just bought a new heater core. $72.00. (should have went to auto zone). I'm going to tackle this on Sunday. I'll take some pics for anyone else that needs them....
**** I also won a kit on e-bay for the heater box doors. It has seals and new pre-cut foam for the doors.
