I personally know where A 68 BB Camaro is sitting right now that was wrecked badly many many years ago and parked behind A mech shop in TN. The owner has every piece of paperwork on the car but thieves stole the VIN and Cowl tag and A few other things that were on the car.The engine was gone when I saw it but I cannot remember if he said he pulled it or the thieves took it also. I am sure these have been installed on another Camaro somewhere. The only thing they forgot was to cut the hidden vins off the firewall, they are still attached.
