QD-16 Cylinder Head Core Plug

[Bob Wight]

While testing the water pump on my QD-16 resto project, I find the lower core plug on the cylinder head is leaking (see pic).    My parts list shows a part #19-51 but I can’t locate a replacement using that number and I find no superseding number.  The plug is approximately 5/8″ diameter.   Anybody have a current part number?    Also, what is the best way to remove the old plug?
