thermo time switch part#

Does anyone know what the part # is for a 78 thermo time switch. I dropped my thermostat housing and the connection broke:disappoin . I was testing it before it broke and I wasnt getting good readings anyways and on top of that the bolts broke of in the bottom thermostat housing part, if its not one thing its another:sick: . The #'s on mine are A23-601000 and it says 19.5 degrees C and 9 sec. It also has 9315 and JECS on it. I just want to know if this is the right thermotime switch. Thanks
