Im looking for a new temperature sending unit for my 1967 WM300 with 251 engine. I measured the threads on the old one ond it measures 1/2 inch where it screws into the head.I got a new one from napa and its way to small. I know its a electro magnet type gauge in the dash is this a special sending unit. Thanks for any help. Milo
