Hey gang..

Looking for a source for the proper plug that goes into the water pump housing on a '69 big block ( my case 426 Hemi, but it should be the same on any housing in that year, if not more years ). This is the plug that people usually take out if they are going to put a mechanical temperature gauge in, in between the two heater hose nipples. I believe the style was flush with the housing with an allen stock recessed hole for tightening.

Thanks.
