Maybe I am seeing it wrong, but it looks like there is an alignment shank below the tapered seat, and at least one has been bottomed out ... not to say the crappy stainless or whotever covers is a good idea ...
My Mustang uses these worthless things too.

A set of Mcgards is on the bench.

I had a 66 Charger, don't remember it having a shanked lug.
