1969 Dart GT vert Cragar REAR wheel size help needed

I thought that the Cragar S/S for the 4" bolt pattern were made specifically as a "special" wheel. I know they have a unique look to them. The ones I had like 10 years ago took a regular shank type lugnut. I do not think they should be specifying a "Uni-Lug", or whatever those stupid things are called!

I thought so too... but this is how they list it now. Unless I am reading it wrong?
08/61 S/S for 4" SBP are uni-lug
61 C S/S only for 4.5" are direct-fit
