1968 Barracuda dash pannel light holder

I checked the Help section at AZ and AA,, they both had the 1/2 inch version, which I recognized as fitting the dash in my '83 D150,
but neither had a 5/8 inch version.
Went home and checked the Dorman web site, I could find the 1/2 inch version there but not the 5/8 inch.
Went on e bay and found NOS Dorman 5/8 inch instrument panel sockets, the part number on those packs is 643-020, that
number is not recognized at the Dorman site. I am not saying that the 5/8 inch sockets are not available as new-new stock, saying
I could not find them.
