Temp gauge install

I have a 1938 stock flathead and a new temp gauge. Need to figure out how to install temp bulb in stock head. Is there a screw in seat or adapter available? Or what?
 
The original bulb has its own screw in flange. Some later ones had an adapter, not sure which. Don't know what you have, but likely not original.
 
Here is the brass adapter that I used. 12 volt on the left head and the original 36 in the right head. Ed
