On the title page of the first section of John Mahoney's book "Full Tilt" is the car in question. This was Kenny Lay's "Lay's Transmission Spl." that Rollie drove and it was indeed one of Charlie Alfater's creations. When Rollie left Lay to drive for Ron Kilman he wanted a new car since he had crashed and broken his leg in the Alfater and wasn't interested in driving another one. That was when he started to drive the Ron Ward car. Karl Busson also drove an Alfater in USAC for his father-in-law, the Bernie Cedoz #95.
