Looking for old magazine picture

[wilyunu]

Good morning fellow board members, I am requesting your help in locating some pictures of a 69/70 ? C10 that I believe was a concept vehicle. It appeared to have a camaro front clip on it, and the photos depicted were of it sitting at a show, and iirc, it towing the camaro on a flatbed trailer. I have seen these photos on this forum, but alas, the search feature did not yield any pertinent results. I appreciate all of your assistance, Mike.
