Stop in for a cup of coffee

Those look like the standard old Mopar instrument light sockets.
and every other company too I think. So I thought - no problem. I have small collection taken from junkyard cars. They were all for 5/8" diameter and these are 1/2" diameter. :BangHead:

I was correctly told this generic Dorman/Connectite socket would fit. It just doesn't work. Little details.

I think Chrysler did use a 1/2 holder for some years. Not sure which ones.
