Optional Studebaker magnesium wheels on both the Comstock R-model and the Falcon. I think your date is incorrect on the Mosport 1966 photo....Comstock racing only had those "Studebaker wheels" (15x6) on for an event or two in early 1965 and switched to the standard American Racing magnesium wheels (15x7) from then on. The same "Studebaker wheels" were run on the Comstock Notchback for only a few races also.
The Falcon had the IRS rear suspension and was a prototype used for testing only....an idea that was being kicked around as something to be done to the Shelby GT350 since the platform between both cars was similar, but the expense/costs and lap times proved otherwise to the accountants back at Ford. Also, as an educated guess....I don't think this IRS Falcon had anything to do with the Bob Johnson Falcon that he ran in 1967....the extra expense to convert it back to stock rear fenders (IRS Falcon has cut rear fenders for easy wheel replacement) and a standard straight axle rear end, which would make it legal for Sedan racing....?
Yes on Ken Miles in the Cooper Cobra.
No on Bob Bondurant in the chair, etc.
