Ac heater box rebuild

Sorry to be confusing. I'm not implying 1970 only, just that the referenced part is correct for 1970.

I don't recall, but I think the idea is to seal around the heater core so that air goes THROUGH it, not AROUND it.

Test fit it into the box to see if it looks like it would seal well.

I do remember that my replacement heater core had fitment issues from the flat plate being attached crooked when it was made, and I had to trim one edge of that plate or something for a good fit.

I had the same problem with my heater core, one lip did not fit flush, so I had to tweak it alittle

My 71 has the same part number on the swing piece.  It also has 3441849 then 82261 2 on the main part

what style nut goes on the studs that are on the A.C. box that hold the blower motor?

 Just reading through this interesting thread.  I'm having my Challenger convertible's AC system restored.  One thing I noticed in the thread that needs updating.  Tav shared some of the late Jules notes, including one where he says new evaporators aren't available so you must have your original rebuilt.  I bought a new one from Classic Auto Air this summer.  It wasn't cheap though, iirc $299. Thought I'd pass that on.

Photos of the mounting nut for the blower and the special washer that goes underneath it.  These are from a 70 Challenger a/c box.   It doesn't show well in the last picture, but there's a rubber gasket/seal between the blower motor and the box.   This one was cut from a 1/8" sheet of rubber purchased on eBay.   The last picture shows the correct seal, but based on previous posts no one makes replacements.

These are pictures of my heater box as it was taken apart.   There are probably some repeats of views already posted but these may fill in a gap or two.

A few more...

These pictures are after the clean up.   The spray paint shown provides a reasonable match to what I believe the original color.   For the vacuum pods, steel wool was used to brighten them and then they were hit with some clear coat.  Overkill?  Yes, but I was on a roll on at the time.

I'll try to fix the orientation of the pictures shortly.   Never seem to get that right.

Also, the drain tube on this version needs to be shortened about an inch.   It's a repair job gone wild.

that's what I needed.  thank you

I have that rubber gasket between the wheel and the motor. this one came in my rebuild kit. does it replace that rubber one or go between the firewall and the motor?

[Dakota]

That foam piece seals between the motor flange and the firewall.

Thank you

I installed the heater box and went to install my dash and I realize I don't know where the heater cable hooks up to? anyone have a picture of where it goes on the box? also is the end that hooks up to the controls held in by a plastic clip?

If you are talking about the cable that controls the temperature, it connects to the water valve that bolts to the passenger inner fender in the engine compartment.
