One of the first things I noticed was the 67 style tailgate and bumper. From my experience a good position of 67's still had the first year 66 tailgate and sometimes 66 bumpers too. Now one can't be dogmatic on mix and match parts because all the manufactures would use up old inventory when making changes. But seeing this early 67 I would bet it had a 66 tailgate & bumpers. My biggest clue is the lack of snaps across tailgate beltline for the Whitco soft top. Odds are this truck had a mishap / accident sometime in its life and the bodyshop just bought what was available... 67 tailgate and bumper. Also what another clue is the "white" painted rear license plate holder which should be body color.
I agree with Drew the rear wheel flares makes it look all wrong. Not to mention the left/pass. is off and running up hill.... I guess "Eileen" installed that one.
If your going to ask top dollar you better have everything correct, working, and darn near perfect: no wiper motors, no washer bottle, squirts aren't hooked up, no jack assembly, rear seat where they shouldn't have one, no seat belt for the rear seat, the rear seat has 68 style armrests, wrong horn button... etc ... etc I'm sure there is more to find wrong, if it was seen in person. What strikes me the fact is "12,000 original miles" vehicle but yet actually has a lot wrong with it!
Oh well, each to their own but it prove to me yet again the Bronco community needs to get into "print" standards on restorations... what's correct or not. Most other classic cars have these kinds of books / resources but its time now for the '66-'77 "Classic" Bronco.
