The purpose of the Boss 429 Mustang World Registry is to gather and compile accurate historical information about these rare Nascar Mustangs. The registry was established in 1974 by Stephen B. Strange, and with the help of the Ford Motor Company, Kar-Kraft engineers Fran Hernandez & Don Eichstaedt, and enthusiasts the world over; have been able to put together correct historical details, photographs, and statistics about the famous Boss 429 Mustang. We still need your help though, in gathering missing information & photos about the program. Today, we are working on publishing a complete Boss 429 Mustang World Registry book, ISBN 0-931417-04-X, scheduled for publication later this year.

Kar-Kraft as it looked in May of 1969. Located in Brighton, Michigan, here Boss 429 Mustangs were hand-assembled, for shipment to selected Ford Dealers, all over the United States.
