67 GT500 dual exhaust cutouts

I really don't know the cutoff date, but it was fairly early in production. You said you have 3 holes. Is the cutout fm the factory dual exhaust setup or is your valance been "hand cut". Mine is an early car and when the trim is removed, you can see that the cut out is very rough.

 

#910 really isn't that early, but from what you described, it certainly looks like yours had the 65-66 modified GT trim rings.

 

Mine is #330 and it has the chrome rings. It also has..

the steel frame/fiberglass hood.

 

The exhaust trim is indeed a 65-66 oval bezel, cut in half...
I own car #130...with the trim bezels...when I restored the car in 1982, it surprised me that they had used these bezels...

Not much written info in the early 80's on early '67 cars...

 

Built in March of 1967, it would seem unlikely your car was built with them. But the holes are there, so, maybe it was a special project set aside that didn't pan out. Or, some new cars just have problems, maybe yours got built, then set in storage, the battery went dead, and nobody wanted to deal with changing it.
The evidence, as already mentioned: the curves are hand cut. If yours don't look that way, maybe the next owner(s) decided to put them on. Doesn't matter, the holes are cut so put them on.

By the way, there is very little about this car in the registry, so mail in what you have, so it will get into the next registry...which is coming soon.

 

Roddster's explanation is plausible. Not sure if it's possible, but you could ask SAAC if your Ford vin is within the range of very early cars.

 

Let me explain further for 2 reasons:
1) I used to work at the Chicago Chrysler pre-delivery center starting in 1970. Some cars just did not run well, or, the battery went dead so it sat a week or two.....or three.
2) I've studied the registry and, some, but not a lot, nor very many ,67 Shelbys somehow got finished or shipped somewhat out of order.

A Marti report might give some more concrete dats as to build dates and shipping. Get one at www.martiauto.com

 

Here is another thing to scratch your head about......... I have noticed that the 67 Shelby's with the Chrome Trim and In-Board High Beams also had a differant High Beam set up. I have photos that show the High Beams were mounted where about a half inch stuck out of the Grille and had a thick Black Trim Ring where as the later 67 Shelby's had the High Beams mounted Flush with the Grille and had a flat Trim Ring that I think was Chrome.

 

Yep, that is typical of the first few cars. It's called a one-piece grille with black trim rings for the center lights and body-colored outer trim rings for low beams.

 

If you think in terms of - the enter 1967 production as a running production change, it's way easier. About every 300-400 cars something changed. You have to own one to care, and them also go look at other 67' Shelbys.

 

Usually workers are considered Numbers. So the 142 could be the assigned number of the person who was working on or inspecting your Shelby.
