67-69 Darts generally look the same to the common folk, as do 64-65 Barracudas, and 66 if your looking at the back. I think he's just found the odd 67 parts before the steering changes in 68 took over. Not sure if Dart panels changed although the grill is different configuration (eg. round parking lamps) but may be same shape.
There are many parts , good, fenders, windshield, that are interchangeable with a 68 or 69 dart , but the 67 is in a class by itself & that is what I'm trying to remember, the term used to describe it
