Engine Temp Gauge

[jdrader2]

Hey all. Things are progressing well on the woodie. The last thing on the list is the temp gauge isn’t functioning.  The place my shop uses to repair them is like a year out.  I think my options are to try and find an NOS part, a replacement part from a vendor, or a different repair place. I searched on here for all three and came up short. 
 

Any suggestions for a 1950 Dodge B-2-B108 temp gauge?
