3/11/25:
I did some (re)engineering this weekend.
I bought an NRG Hub adapter for the steering wheel, I Also bought one of those steering wheel disconnects and a new wheel as the old one was well, big, old, grody and cracked. It would turn my hands black from the eroding Black Plastic on the surface.
I am not sure if I have any good pictures of the old wheel, I probably do somewhere. It was a well used Stock '64 Dart Wheel.
Here is a cute one from a while ago:

Well the hub did not have any provisons for the Horn ring / wheel contact also no way to cancel the Turn signal cam which are both super annoying and non starters for me in a street driven car. No dumbass horn button under the dash for me on this build.
I built a horn ring wheel/ donut contact from an existing part that was pulled out of a 1981 Chrysler Lebaron Station Wagon. I found that the Copper donut was really Copper plated Steel, so that made the fabrication much easier. I built a mounting ring to bolt to the back side of the NRG adapter, and welded the old MoPar Lebaron Part to it. The assembly got bolted inside the NRG adapter with plastic isolation washers on the top and bottom to keep it from grounding back against the Hub adapter / Steering shaft which is common with the chassis ground.
I also did some careful measurements of the existing turn signal cancellation nub on the factory wheel and was able to spotface and Drill the hub for a 3/16" roll pin.
It has worked well so far, but I have yet to drive the car until I get the Hood back from paint again.
Backside of the NRG 170H Hub adapter:
No Provisions for horn etc except for a wire pass-thru.

OE style wheel with Horn donut contact and a turn signal cancel pin:

1981 Chrysler Horn Donut contact: copper Plated steel. (sorry for the bad picture)


NRG hub with Soptface and drilled for 3/16" Roll pin for turn signal cancel function.

NRG Hub adapter adapter and contact donut complete.


Comparison between OE and Not OE, sorta made by me.

Install complete:

Removable as well - Will help with those pesky under dash projects!


Now that it is not so cold, snowy and deary out I cant wait to get the hood back from paint!
