Radiator drain
I want to use the original style petcock on my 71. The new radiator is brass and copper but came with plastic trans and drain plugs. The problem is it is not 1/8 or 1/4 in npt.
To small or to large ,it is something in between such as 18 mm so I'm looking at this... http://www.jegs.com/i/Be-Cool-Radiat...oductId=744291 The best measurements I can come up with on the plastic plug threads is 7/16" od and 20 threads per in.
