They were used on a ALL MoPars that had exposed lug nuts, back in the day.
Corrected.
The Lug nuts that came on these cars had the stainless cap on them (or I think they are stainless – not really sure).
They are a royal pain in the rear, and (in my opinion) worthy to be removed from car at very first opportunity and replaced with the other nuts (mentioned in earlier posts).
Personally, I prefer the one in top picture.
If you are really committed to using the OE style (but cheaply made), the OE part number is 6031535 (MSRP as of March 1, 2018 is $10.20 (US) each) - need 20x.
Note: I have some nuts I removed from my ’87 Dodge Daytona Shelby when car was brand new (again, to get rid of those as quickly as possible) and still have some remaining (or I think I do, still). I’ve used a few of them so don’t have a complete set.

If lug nuts are shiny, I don’t know of anyone who goes around and looks to see what kind of nuts you have.
After a couple of uses, the caped nuts (OE style) no longer look shiny, no matter how much you spit polish them.
