I've got a 65 GTO I bought back in 1983 that is believed to be a Royal Bobcat. Here is what I know: Was originally bought at the Ace Wilson Royal dealership in MI. Have the original books along with documentation from PHS. Engine is a 421 tripower "SR" service replacement motor, but have no documentation if it was done by the Royal dealership. PHS can't document if the car is a Royal Bobcat or not. They were only able to provide the build sheet which shows a 389 tripower. Color was originally burgandy with red interior. Can anyone help with this puzzle?
