I've heard a lot of debate on the yellow stripe on the hood, so I can't say for sure. I have heard that they stopped when they changed the decals, I have heard it depended on how much help they had at the time.

There is a difference in decals, your 66 should have the early ones. You can get them through <!-- w --><a class="postlink" href="http://www.oliverdecals.com">www.oliverdecals.com</a><!-- w --> . Give them a call, and Lyle or Helen might be able to give you a better answer on the hood paint question you have.
