Harden finished 5th in his 5687cc. ex-Dave Ridenour car.  

The best Genie photos I've seen so far are on "Huffaker Racing's "History" page.  The Genie photos are from Cotati in 1963.  Ridenour is in the #146 car, still Oldsmobile powered at this time.. The #448 Chevy-powered car is driven by Jack Dalton.  Lower down the page are two priceless shots of the earlier front-engined "Huffaker-Chevy" in action.
