KK1201 - The 1st Boss 429 Prototype

[69hurstSC]

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.

Keep us posted on the progress.

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

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.

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?
