K codes by the numbers

I know we don't have exact production numbers, but is there an idea out there about percentages?

What percentage Mustangs produced in '66 were K Codes?

What percentage of those Ks were used as Shelbys?

What percentage of Mustangs in '66 were FACTORY GTs

What Percentage of Mustangs in '66 were FACTORY Pony Interior

What Percentage of Mustangs in '66 were convertibles

What percentage of Mustangs in '66 Were K code convertible GTs with Factory Pony Interior.

People always ask me these questions about my car, and I was going to design a new display board that attempts to address the rarity of K codes and of highly optioned K code cars such as my GT convertible.

Thanks for any help/light you can shed on this.

Agreed, but that's not the point of my thread, nor is my car an impostor. That's why I am trying to keep my car as stock and original as possible so I can preserve how it is supposed to be for those who care to know what a "real one" is. I did take some liberties with some interior changes, though. My original door tag is still intact, which verifies the colors and options. I can't prove it's a GT with a window sticker, but I can't prove it isn't one, either. Everything is correct. I still have all the original GT trim components including fog lights, wiring, and gas cap. I chose to clean them up the best I could rather than replace them, even with their pits. My car has never been fully restored, either. Still has 95% of the original sheet metal as well.

OK, one way to look at the numbers - Am I totally wrong here..??

There were 607,568 Mustangs built for '66 model year. I'd say that's a pretty large sample to base estimated percentages on using the following figures which I assume are facts...

~9% of '66 Mustangs were convertibles

~2% of '66 Mustangs were convertibles with pony interior

That makes total production of pony interior convertibles at 12,520 (Mustang Ranch Source) before taking into GT or K code equipment.

According to this website, there were 5,469 K codes build for '66 model year.

There were 2,378 GT350s produced for 1966 (Mustang Monthly source), leaving only 3,091 non-Shelby K codes. These are know production facts, right?

If the above facts are correct, we then can start to estimate based on what we know is in both (a) the current registry trends and (b) production trends from a sample of over 600K units.

The registry has less than 6% of all '66 K codes as being convertibles. Compared to the total production of '66 Mustang convertible percentage of about 9%, I'd say that's pretty close. It stands to reason that more K buyers would seek a more performance based body like the fastback over a convertible. There must be a reason why Shelby also chose to use the FB instead of also making verts. Let's assume that 6-9% is realistic.

That puts us at 185-278 estimated K code verts for '66 Lets call it 278 for the sake of generosity.

Based again on total production percentages, even fewer would have been built with Pony interior - at 2%, that gives us about 62.

So, before taking into account GT status, we have only an estimated 62 K code pony interior convertibles produced. That's about .01 % of total '66 Mustang production. That seems low, but the math seems right unless I'm missing something.

Who knows about GT at this point, but that's gotta bring the total number of Pony interior equiped K code verts with factory GT cars in '66 to less than a couple dozen. We won't even get into color combinations.

How's my logic? Feel free to correct me on this stuff. I realize it's all an estimate, but we seem to have good data available to make some educated guesses on this stuff.

I need clarification on the K codes vs Shelby numbers....

Since they don't include Shelbys, I'll have to redo my math!<img src=images/icon_smile_dissapprove.gif border=0 align=middle>

Using previous estimate logic, I get the following estimates for '66

1. ~492 K code convertibles

2. ~109 K code convertibles with pony interior

3. ~230 K code GTs (all body styles)

4. ~46 K code GT convertibles with pony interior

So, perhaps I can tell people that there was an estimated 50 or so GT K code verts with Pony interior built from the factory in '66.

Don't worry - I won't get too hung up on the numbers. If I were that hung up, I wouldn't let my 3 and 4 year old climb in the backseat, throw a stroller behind me and hike around the park and get ice cream later with it! You should see how people look at me when I show up for cruises and shows with my two kids and car seats in the back!

I just want to know what to say when people ask. I also thought it would cool and educational to make a display with some K code facts and be able to add some production stats.
