What are these for ?

Sliding over from B-Bodies with a question.

Cleaning out my stash and found some L/H thread wheel studs and nuts.
I know they're to short for my RR.
1/2 x 20 thread
Overall length 1 13/16" (close via ruler)
Thread length approx. 3/4"
I'm sure they are Mopar as the studs are copper in color as mine were for the RR.

Any thoughts?
Thanks
Frank
