[Healeys] Thread Size for Overdrive operating Valve Plug

[jpaynepbr at cox.net]

Anybody know what the official size designation and thread is for the
Overdrive Operating Valve Plug?

 

Trying to fit up a pressure gauge, and having issues finding the right
adapter.  The Major OD of the plug is .49", and the British standard pipe
taper and parallel major OD is .51", so they aren't going in.

 

Thanks, 

 

Jonas
