got to figure the first few were show cars then the next group were for crash testing then they went to the general public after that
maybe yours was an early show car that was sold or one that was to be crash tested but it wasn't, who knows
like with the Boss 429s KK numbers xx01 to xx12 were show/crash test cars then the rest were sold to the public, and if you got an early one you got Nascar engine components, my fathers has the luck of being the highest recorded survuving KK number from 1969 but the vin is not. figure they were loaded onto the trailer lowest vin first so when they came off they went into Kar Kraft highest vin to lowest for the shipment and were thus numbered as they came off the line
