Many ERT 1965 cars had the battery relocated to the trunk, which was changed mid-year from complaints of fumes, and had over-rider traction bars, relocated A-arms, as well as other modifications. Over-rider traction bars are named so because of their design being on top of the leaf spring as opposed to underneath them. There was only one transmission available, a 4-speed Borg-Warner T10 manual. The exhaust system in the 1965 GT350 was a side-exit dual exhaust with glasspack mufflers. For this one year, the GT350 also had special -rated Goodyear "Blue Dot" tires, named for the prominent blue dot on each sidewall. The 1965 GT350 had a full size spare tire mounted in place of rear seats, making it a 2-seat-only vehicle (to be allowed to race under SCCA regulations as a "sports car"), and rode on either silver-painted steel wheels or special cast-magnesium center "Cragar Shelby" 15" rims with chromed center caps marked with a stylized "CS". Total 1965 model year production was 562 units.
