Roger,
I read the following from a post you made about four years ago:
Ron when I replaced my coil the normal replacements wouldn't fit under the air cleaner. Can you tell my if your coil fits under the air cleaner or does it stick up behind the air cleaner? Me original coil was black and it was 3/4" shorter then the replacements we get today.
I just bought a 67, and I am having this exact problem, among others. Did you ever sort it out?
Cheers,
Jon
