Hey Ken, saw this is your first post and forgot to welcome you to CHR! Hope that you don't let the third person replies put you off, and that you'll stick around and keep everyone here in the loop on what you're doing with the Chevelle. There is a wealth of good information you can glean if you stick with it and keep focused on questions you may have.
