I disassembled an early October 1964 (1965 year model) SJ Coupe that I have, and found a strange fastener. It was the top passenger side bell housing to block bolt. It had a stud on it. I have attached a photo. Has anyone seen this before? The length looks exactly the same as the others, which have no head marking, and appear to be original. I am guessing it held the clip for the automatic transmission vacuum modulator line, but I am not sure. The car was partially disassembled when I got it. Thanks in advance for your help!
