> NAPA Part #BK 7011798 I had to file the center opening in the reducer to enlarge it a little to accept the bulb. Other 'Bolters say that their temp probe fit through the reducer with no problem. My temp gauge is a reproduction, possibly a little different size than the original.
Mine is in a Dec 22, 1959 "848" head on a '54 235, '54 reproduction temp gauge from the Truck Shop.
