And if it was a Gran Sport the fenders would have had holes welded up, long rectangular holes, three or four of them where the "gills" mounted at the back near the door below the body line. There were no side mouldings on Gran Sports, but also on Specials there were none.
If it is a 64 or early 65 it would have had holes all down the body for these mouldings, mid year 65 they went to the studs to mount them. The 64 and early 65 also had a down flow rad where the late 65 had a cross flow. I could go on and on with Gran Sport stuff like the battery is mounted on the left side and the skylark is on the right.
