Dash Light Upgrade Question

[CDT540]

I am trying to sort out my instrument lighting as to why some work some don't. The original light sockets that are one wire and ground themselves to the speedo are the problem. Two of the bulbs have been changed to a updated socket shown in the pic that utilizes a wedge bulb and is a two wire so it can be directly grounded. Those are working fine and I would like to change out all the original one wires but I can't find these anywhere. There is no manufacturer on them but they show what appears to be a part number PA66. In the end I don't if what I find is not exactly like this one as long as it functions the same. Anyone ever changed these out or no where I might find these? I check all the usual spots and googled but no luck. Thanks for any help...
