I have a '68 that wont start. I'm wondering if my neutral switch, from what I have been reading, is not connected correctly. The car was originally a power glide on the column. It is now a muncie. Did the '68 have this switch and would it affect my starting problem and how. I hve the purple wire going to my "S" terminal on my solenoid. By the way I have an HEI unit on the car now. Thanks for any advice.
