KK1201 - The 1st Boss 429 Prototype
 

After continued research, documentation has concluded that my new Mustang (9F02R100031) is KK1201. The VIN, door tag, buck tag, hidden fender VIN, block and transmission all match historic paperwork noting this car on Kar-Kraft documentation. For now, it's research, research and more research.

Ed Meyer, Bob Perkins, Joe Spinelli and a cast of thousands have been helping with figuring out the cars history. I've also secured the Eminger reports and the Marti Report, and Kevin is going through his documentation to see if he has anything on the car. We have educated guesses as to what the cars purpose at KK was for (possibly 15x7 tire testing) but want to substantiate that with documentation. I'm also backtracking ownership history of the car (currently stuck in 1994). The car retains its numbers matching 428 CJ engine and transmission.

Some anomalies include blanks on the door tag and the warranty portion still attached. It's also likely the 1st 69 CJ 4-spd, and I've yet to find a car ordered earlier than this one (May 23rd, 1968). The order received date predates the Introductory Show Units (June 4, 1968) by 11 days. The car was completed on June 20th, 1968 and was at the Dearborn Test Track just a few days later (June 22nd). Bunkie Knudsen approved the B9 program on June 20th. There's also a significant gap in registered CJ's after my CUN (100031) with the next being 102205. What does all of this mean is anyone's guess, for now.

The car was also sent to Ford Design Studio fabricator Paul Shedlik for usage of creating the mold for Ohio George Montgomery's 1969 Gasser.

It's also looking likely the car was used for SS/E testing by FoMoCo.

I'm looking forward to finding out more about this historically significant car and gathering info about the very early beginnings of the 69 CJs. To date it's the only Boss 429 prototype to surface.

If you have any paperwork pertaining to the 7 original R code B9 prototypes (plus the no Number car) I'd love to hear from you.

When you announce the existence of a car like this it is an uphill battle. I found this out first hand with the research surrounding the first 1967 Camaro assembled and then through the documentation of the remaining 1967 pilot cars. Research is key and being sure to close every loop in the process while you are at it.

Owning the last of something can be easier, when you have video documentation of an empty build truck following the unit. That is iron clad.

Congratulations on your find. There will be a few who might toss a stone here or there, but stay with it. That looks to be a significant car you have there.

Great find! That's a special Mustang there. Good luck in your search for information.
Keep us posted on the progress.

Very great find. Was it sent to Kar Kraft with the 428 engine & did it retain that engine?

place holder

Wow....wow....wow.....Just, WOW!!!!:eek2::eek2::eek2:

There needs to be a bigger :eek2::eek2::eek2 emoji for me to use!! Incredible!!!

And where did you...how the....what the.....??:hmmm:

Can’t wait to see this one restored!!

Double Cheers to that one!! :beers::beers:

Hi Bergy. From what we've been able to gather that's unclear at this time. As you see the door tag is sans color and driveline info. We're trying to figure out what came first, the door tag or the buck tag. The Buck tag is filled out as a Mach 1. The door tag, what little info is on it, lists the car as having the standard 63A Fastback interior.

But to answer your question, yes, there is a numbers matching 428 drivetrain in the car.

Removed

Exactly! Keep plugging here and tell everyone why.:beers:

CONGRATULATIONS!!!
Killer find...
PLEASE Give some back story...
Did you buy it knowing it MAY BE special or was that a bonus?

I do not know much about Boss 9's - I had assumed they were shipped to KK sans engines, were they shipped as complete cars with 428 CJ's? then altered?

Sorry don't, mean to insult anyone, but please explain to me what this car is? I caan follow it's a KK numbered car, but if it retains the #'s matching 428 what would be related to Boss 429? Are the shock towers moved like a Boss 9?

It's a prototype. 1 of 7 prototype Boss 429s. Each car had its own purpose in developing the Boss 429s.

If you look at other EARLY prototype Fords from this era 1201 falls right in line with them. Shinoda's Boss 302 prototype had a 428 CJ. The Boss Bronco didn't have a 302 or 429, it had a 351 Shelby engine. This car retains it's numbers matching 428 CJ.

As stated earlier we're continually seeking information and researching the car. We know the car has rolled fender and quarter lips. The build date was exactly the same as Knudsen greenlighting the Boss 429 program. Due to the massively condensed timeline Ford had to get quite a few balls (Mustangs) rolling to move the project along with expedience.
It's likely this car was built in order to get the 15x7tire/wheel combo rolling. It may have also been a test fitment car for the 429. Maybe something as simple as "Let's test this 429 to see if it fits in the brand new 69 Mustang body". Remember, as of August 20th, 1968 there were likely ZERO 4-spd, staggered shocks cars in existence beyond my car.

So what I've been doing is posting as much information as I have on the car in as many places as possible in front of as many experts as I can. Doing this yielded the information on the car being used as the molding mule for Ohio Georges 69 Gasser. It's my hope that more solid documentation will come forth regarding the cars time at Ford, which seemed to be the whole model year.

What we have for sure is hard documentation with the car on a "BOSS 429 VEHICLES RETAINED FOR COMPANY USE" and a "BOSS 429 VEHICLES" list. It also appears on lists for "SPECIAL VEHICLES ACTIVITY DEPARTMENTAL VEHICLES", "1969 428 CID COBRA JET MUSTANG - SPECIAL" and "STOCK VEHICLES DEPARTMENT SPECIAL VEHICLE ACTIVITY - VEHICLE ACCOUNTABILITY".

What was your question again? LOL

Lol thanks. I have no idea about Ford stuff. So are the shock towers moved?

No. Any of the altered shock tower prototypes would have likely been destroyed. This is the only confirmed surviving KK car, 1201 thru 1207.

This is quite a find and rather amazing it has a numbers matched 428 in it if it was used for drag racing and a Boss 429 test car. If the towers aren't moved the Boss obviously never got installed.
That mostly blank data tag is bizarre too.

I hope you can keep us updated as you find out this cars history.

wow!! awesome find! look forward to following this one!

Agreed. When Mustang experts tell you they've never seen another like it you're left wishing your car could talk.

I wish they could talk. We'd probably hear some crazy and cool stuff!

Wow, what a great find. Interesting tag and I notice it doesn't say it's a VIN. Does the car actually have a title and registration?

Wow they parted out Bunkies

So where is the body??

The body went to the salvage yard. I've been working on tracking some of the parts that remained.

Mustangs...
 

Following this story...how much horsepower did these big engines really make??

boss 429, 428 scj, etc....seems like what I have read has them 'under-valued'...

thanks...wilma

1201 was invoiced twice to the Dearborn Test Track with August 23rd (2nd was October 17th) being just 3 days after Bunkie authorized the build of the Boss 429s. It's important to note that at this time 9F02R100031 was likely the only 1969 4-spd CJ that had been produced. All other 69 CJ Mustangs up until that point were automatics slated as Introductory Show Units.
