Does anyone in barn land know, what the female end,thread is for size? On mind it has a brass female nut that secures the temp bulb into the fitting that goes into the upper radiator hose.I can make the radiator adaptor if I can find out for sure that female thread size.There are pictures in the 33-34 ford book by Cliff Helling on 5-19 & 5-20 any help would be appreciated.Thanks EPW
