Any Tuff wheel adaptor experts out there?

[1MeanA]

I bought a Tuff wheel adaptor only to find that it doesn't have a master spline. I sold it to someone who tried it on a 4wd non tilt column and it didn't fit so I took it back. It looks the same and dimensionally seems the same as my repro Tuff adaptor that fits my '70 Dart with exception of the master spline. I don't see a part number on it. There seems to be no definitive fitment guide out there. Any idea on what this might fit? I might have to go to the wreckers (if I ever get time) and find a 2WD D150 to try it.

Do you know what year 4x4 column they tried it on? I have an adapter without the master spline and it fits on my '72 W100 and '73 W200
