Its normal practice to have them together at a GMAD plant like LA and Lordstown where the assembly process was combined into one long assembly line with a single paint and trim shop, but not in Norwood which had separate Fisher and Chevrolet Assembly plants on the same site. The jig that the fenders are attached to is probably pretty similar to the Chevrolet side equipment. I can't see where the hood and the upper and lower valances are from that picture though. Take a look at the third car back in the video where they are spraying the Camaro, its a 4 door sedan, Unless they were making 4 door Camaros at Norwood in 67 thats not the Norwood paint line (besides Norwood Used a Towveyor system to send the cars thru the paint line, they didn't hang them from an overhead conveyor system, LA and Lordstown did that. I can get a screen capture from the video and show the car in question if need be. Of course the pilot car site never said it was Norwood we are just suppossed to see a Camaro being painted and believe it is somehow related to the pilot cars. I don't know what the Plant 21 paint line where the pilot tubs were built looked like, but it seem like that picture would be more of a full blown assembly plant line, not a limited production facility, and you would think they would only be working on one line of car bodies at a time there. Some people will try to say that this is a picture from the 66 production line at Norwood, but its a known fact that Detroit Plant 21 provided FULLY PAINTED AND FITTED OUT TUBS (finished exactly as if Fisher Norwood would have done if they built them on the line) to Chevrolet, so this picture cant be of the pilto cars being fitted into the assenbly line at Norwood (or LA or anywhere else) becasue they were already finished as far a Fisher was concerned when they were delivered. So, if this picture is not Plant 21, and not the LA paint line, then its Lordtown and thats not even a Camaro being painted, its a Firebird, but the picture is definately not taken at Norwood in either 66 or 67.
But I guess , does it really matter, the guy is showing some assembly plant pictures with a Camaro in it, so i guess whether its the correct plant or not only matters to freaks like us that want to know the name of the guy that tightened the lug nuts on the cars we now own, not to the 99.99999999% of the rest of the world that can imagine what it takes to get all those little parts together at the right time to assemble 1000 cars a day, every day and have most of them actually get built correctly, day in and day out..
