Don't remember the name of magazine, but I think it is Mustangs and Fords, the current issue I just bought off the shelf a week or so ago has an article on a restored trans am cougar. Lots of pictures.....hope this helps........Keith
Modified7 is right, "Mustang & Fords" magazine has an article called Racy Kitty in the May issue.
You may also want to check out the TCCN (The Classic Cougar Network) webpage at http://www.theclassiccougarnetwork.com/tccn/frame.html.
You have to be a member, but for what it's worth I think that it is well worth the $12 annual fee.
They have a Racing Heritage section that has some pictures of of the TA cats, as well as other intersesting facts, pictures and tech tips. If not for them I would not have found this site!
