I use the location to help identify a factory GT(I'm aware of all the factory modifications). I've come across a 1965 that has all the factory mods, every single one, including the support inside the rear frame where the holes are for the hangers, but the GT emblem is further back from the fender than usual. I assume the '65 had the emblem in the same place as '66....or was there some variance between assembly plants?
