Default 1966 owners manual question

For the 1966 Corvette, when did the second edition owners manual replace the first edition?

Welcome to the forum. The best source of information for that kind of question would be to check with the NCRS organization.

If they can't help, you might try the NCM.

Thanks, I got the answer from my NCRS 1966 restoration guide. Mid January, 1966 was when the change occurred. Thanks to all.

I was going to guess it was probably in the fall of '65 around the same time they dropped the horsepower on the 427 from 450 down to 425. Glad you were able to track it down.
