The ’69 Mustang Mach 1 took the place of the GT and proved very popular, combining racy looks with luxury trimmings. As usual, the high-performance models were more expensive and correspondingly rare. Only 1,934 buyers ponied up $3,450 for a Boss 302 and 857 buyers paid $4,798 for a Mustang Boss 429. The Boss 429 motor was a heavily modified racing motor that Ford wanted to homologate for NASCAR racing, and all were built at Kar Kraft in Brighton, Michigan. These homologation specials didn’t scream performance with their relatively subtle badging, but they were blisteringly fast. As was customary in the 1960s, their 375hp rating was highly conservative. Those in the know looked for the Kar Kraft “KK” number and the NASCAR identification label.
Both of those are present and accounted for on this highly documented 1969 Boss 429. Sold new in Kearny, Arizona, a month after being built on February 13, 1969, its Deluxe Marti Report confirms it left Kar Kraft (KK1333) painted Candy Apple Red with a black vinyl interior, along with the requisite Boss 429 performance gear and few luxuries aside from an AM radio. Accompanied by Erminger Build Sheets, letters from Ford and Kar Kraft quality checklists, the car is outfitted with Magnum 500 wheels and period-correct Goodyear tires. In exceptional condition throughout and one of the first 150 examples built, this highly coveted and collectible “Boss 9” is at the top of the Ford performance food chain for 1969. Included for the next owner are two professionally done 2-foot by 3-foot poster boards with all documentation and highlights for your next car show or concours event.
