Scott, great work as always ! you put a lot of time and effort into all your posts.
Earlier in the thread you mention the taller rear spoiler on the '67 car, these two images are I believe else where on this site, I think Jon has them up ? shows the car at Sebring '67 with the smaller (lower) spoiler, a photo from Continental divide with the bigger (taller) spoiler. the text explains a bit about this modification, and why it didn't reappear after a towing accident.
Jon, was this piece homolgated ?, and allowed under the rules, I'm sure you know the details. I don't recall seeing that spoiler on any other car ?
