Freedom Bird

Sgt Ingle is the owner of the 1971 Pontiac Firebird pro-touring car known as the CS-71 “Freedom Bird” which was debuted at the 2009 SEMA show in Las Vegas, Nevada (photos below). Sgt. Ingle has owned this car since his high school days. What started out as a “scuff and shoot” repaint ended up turning into one of the most unique, and “one-off” builds in recent memory. The Freedom Bird is wired from front to back with American Autowire products, including our brand new 1970-1973 Pontiac Firebird Classic Upadte Series wiring kit.
Many industry companies came together to donate parts to the cause. American Autowire was proud to be a sponsor of this beautiful car and wishes to thank all of the other member companies who participated in this build. We would also like to thank Sgt. Ingle for his years of service to our country and wish him continued success both professionally and personally.
