I think I have seen the odd connector. However seems like 99.9 percent or more were always the stud style no matter with or without a/c. If that was true which it must be they would also have to offer the complete engine harness for one connector..Guess I need to look at my 67 factory AC GTX with original harness. I thought it had a molded stud type terminal on the wire but my memory may be faulty.
