I know this has come up before, but I have been away from the site for 4 years. I have a 67, 400, 4sp, some what original, has PHS doc. I have deluxe int. but standard belts, which is legit. My question is about the button, has anyone figure out what is correct for 67? Mine has the GM, but have heard it should be the coach. Could it be different from factory to factory.
