As if the standard GT350 Mustangs weren’t hot enough in 1965, Shelby also built 36 (counting one prototype) GT350R models that year. No compromises for daily use were included in this batch of mean Mustangs. Nonessential items like bumpers were removed in the R model’s case. A special fiberglass apron filled the front bumper’s space. Rear-quarter roof vents were covered with aluminum panels. Photo: Mike Mueller.
