Dodge Dart Lite

Bunch of little stuff.
I purchased a 73 Duster Bench seat locally in Dallas.
It had headrests.

After getting it home it wasn't what I thought it would be.
Duster seat much different from my 76 Dart seat.
Someone had made the headrest slides from aluminum.

So I am going to use the headrest because they are correct, but the slides are weird.
I had found the side catches on facebook.
I could not get the knobs off till today.
If you clamp them in a vice you can hit them with a rubber mallet from the rear they will come off.

I also fixed a cracked mount bracket on the heater control panel I got from Rat Rod Al.
JB Weld and a little piece of aluminum.

Finally I started looking at the engine harness, but I can't find this on the schematic, any ideas?
