I was going to borrow a couple of trim rings from my sister's 67 Vette but they are such a pain to install correctly I decided to go with what I had.
One thing I did notice in looking at cars judged in previous years, is that some of the standards have changed over time. And that's OK but I would still like to see the standards written down like in the NCRS books. I know that will be a huge undertaking, so I will offer my help in any way to be part of the solution.
Keep us posted on written standards progress. I'd love to know how that works out...
