My friend and I laughed at this when he opened the trunk. We had a decades old joke about these stickers.
Back around 1985 he worked in a shop next to mine and we were both doing 68 Camaros. When I was putting mine together I was out back with the trunk open looking at how to put the jacking instructions sticker and he came up and and said, "You know how you put the on properly, just as they did at the factory?" I of course said yeah,how? And he walked away from the car with the sticker and then ran up to the car plastering it on the lid and ran off like a guy would have on the assembly line! LOLOL. And it was a LOT nicer than on this car he had just bought!
