Jon Mello recently posted these two items on the ninth page of the 1967 Trans Am season review thread and I wanted to include them here as well. The following two attachments show the 1967 Camaro RS/SS convertible (possible Indy Pace Car replica) that paced the Trans Am race at Mid Ohio Sports Car Course in Lexington, Ohio on June 11, 1967.
The first one appeared in a pictoral retrospective on page 6 of the official program for the SCCA (Sports Car Club of America) National Races held at Mid-Ohio Sports Car Course, Lexington, Ohio on July 15/16, 1967.
The second one must have been taken at nearly the same time as the one above but from the otherside of the track. It appears in the July 1967 edition of the Mid Ohio track Newsletter.

A close up view of the first picture appears in post #2 on the first page of this thread and a picture of the car during the pace lap appears in post #63 on the fifth page of this thread.
