This is a photo of the interior of the Penske/Donohue Camaro, taken 27 August 1967 at Continental Divide Raceway.
The car finished an atypical 8th, outrun by 3 Mustangs, a Cougar, two Alfas, and a Porsche. This was by far the worst finish of the year for this car, absent dnfs at Daytona, Bryar, and Las Vegas.
The class regulations were somewhat restrictive, requiring an almost complete stock interior, which accounts for the presence of a standard Camaro upholstered door panel, including the swinging vent window, angled to blow fresh Rocky Mountain air on the driver. Also visible are the roll cage braces and a rather anachronistic wood-rim steering wheel. The roll cage had been a relatively new "unfair advantage" innovation installed after the Bryar dnf, and credited, along with a rear anti-roll bar, by Donohue with putting the Camaro on an equal footing with the competition.
The wood rim steering wheel appears to be a remnant of a weekend of continuous problems suffered by the Camaro, culminating in the dismal 8th place result.
Chevrolet engineer Paul VanValkenburgh, in his book "Chevrolet Racing: Fourteen years of Raucous Silence, 1957-1970" says this regarding the Camaro victory at Marlboro, MD on 12 August:
"The 1967 season was lost by then, convincingly so after the next race, where they failed a transmission, a fuel tank, a tire, and the
steering wheel."
The "next race" was Continental Divide.
