MOMOMopar (Did I stutter?)

I guess the trick comes down to finding the right adapter...and of course, old Mopars are seemingly not amongst the official applications.

Is there a known list of cars that has the same column/spline dimensions as a stock vintage Mopar?

Yep, the installation adapter makes all the difference not only in getting the wheel on but how it looks installed.
I had (still have it) a Grant wheel and installation kit, and the hub that the wheel connects to has a soft rubber boot around it that was pretty much impossible to keep round.
Basically it looked like a shifter boot for the steering wheel hub and I hated it.

Then I found a wheel at Big Dog performance parts.
The mounting hub is polished billet and looks really nice, and the rest of the kit was better including the horn button. (not tons better on the button, but not as cheap as the Grant stuff)

I found some round Mylar Mopar "M" stickers online that fit the button perfectly.
The adapter hub/horn ring is also billet, and the install kit was perfect for the application.
