water pump housing plug source

[hemi68charger]

Hey gang..
I'm missing the original plug for my water pump housing. Does anyone know of a source for an OEM correct plug?

The below picture shows the type of plug, recessed allen head..





The one I have is in the picture below. Ok for now, but would like one that's more OEM.

Thanks...

You need the plug with the  recessed square....I'll see if I can crank one out of a core housing AB......This sounds familiar? Deja-vu?
