Gauge plate template:
Taking the base line horizontally through the screw hole centers with vertical (90 degrees) from the needle pivot which is midway between the screw holes, the placement of the temperature markers is as follows:
90 C @ 80 degree angle
100 C @ 90 degree angle
150 F @ 64 degree angle
180 F @ 72 degree angle
210 F @ 93 degree angle
240 F @ 105 degree angle
270 F @ 125 degree angle
The center to center of the screw holes is 0.852" which provides scaling, I think.
If one wishes only to have their gauge display in degrees, check the Thermobob web site as there used to be an overlay for less than the trouble to make one.
The above should be adequate test data to diagnose or determine whether another guage or sender can be adapted.
