What does this A/C part do?? I lost it

I'm nearing completion with my restoration of my '68, I'm now tackling the air box and dash. Trouble is, it seems I lost 2 things while everything was apart.

1. Could someone please tell me what the circled thing is, and if it can be replicated in function, if not in physical aspect? What are those connectors? First attached pic is what I believe is my missing part attached to the box, second is my installed airbox with just a hole where the piece would be screwed in.

2. In the third picture, I have my restored a/c temp control, but I lost the temperature knob. I remember it having a metal rod connecting it to something. Any of you know where I could source that? All I find is the bezels...

Any help would be greatly appreciated

Still in awe of what the engineers were able to do more than half a century ago!

In this picture see the resistor network on the right center...   That lives inside the heater box so it can be cooled by flowing air.  The piece you are missing is the mount and external connections for that resistor network.

The little panel in pic #1 is the blower motor resisters.  They are in the air stream to keep cool.  Can't help on the rest.  Ooops, see that gold rush beat me to it.

Thanks a lot guys!

I found the resistor @ $300 USD, that's damn close to a whole airbox!

I found another one, at $35, with exactly the same number & position of pins as my original one, but for mid to late 70s C Bodies. I don't know if the resistors are the same, what do you think are my chances?

Here's the link to what I bought:

As for the TEMP switch, I bought a whole '69 unit. Alas, it was my only option. Apart for the fact that '69s & '70s have engraved switches, do you believe there is any reason for the switches not to be compatible with the '68 unit?

My Stuff on a 1968 Charger

Thanks John, the info would have been invaluable, had I seen it sooner. I ended buying something I hoped would be equivalent, but in the mean time I found my part.

Thanks again everybody for the help!
