Re: Temperature gauge not working

As I understand it the plate is not going because it still has the mechanical oil gauge mounted. Some of the modern aftermarket gauges have a standard size nut that threads into different size adapter bushing their sensor inserts into. Pick an adapter that matches threads in the hole in the head. If he solders on a modern bulb it may come back that way. If he reuses the Packard bulb, the sealing flange is recessed into the head quite a bit and a different or smaller nut may not be long enough to push the sensor flange against the machined sealing surface in the head opening. Been there, done that when I had to install a temporary gauge hook up on the 47.
