text: Many early 1965 cars had the battery relocated to the trunk, which was changed mid-year due to complaints of fumes, and had over-rider traction bars, relocated A-arms, as well as other modifications. A 4-speed Borg-Warner T10 manual was only transmission available. Dual exhausts exited out the sides via glasspack mufflers (with fourteen cars being equipped with rear-exiting exhausts to meet state regulations for sales in certain areas). 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 qualify as a "sports car" under SCCA regulations), and rode on either silver-painted steel wheels or special cast-magnesium center "Cragar Shelby" 15-inch rims with chromed center caps marked with a stylized "CS". Total 1965 model year production was 562 units.
  1966 GT350
  For 1966, the GT350 lost its Mustang tag and was marketed simply as the Shelby GT350. The new model year also saw the introduction of non-white colors, including blue, red, green, and black. Other changes included special rear quarter-panel windows replacing the factory extractor vents, functional brake scoops on each side, and optional SelectShift 3-speed automatic, as well as an optional Paxton supercharger. The battery was no longer relocated to the trunk for 1966, and the over-rider traction bars were discontinued. The normal factory fold-down rear seat was optional. While early 1965 cars had black engine blocks, 1966 and later engines were painted regular factory Ford dark blue. The 1966 models came with a dual-exhaust exiting in the rear.
  The first 252 GT350s for 1966 began as 1965 Mustang K-Code Fastbacks that had been specifically ordered by Shelby American for conversion into 1966 GT350s; these all had 1965 bodies. They were received in blocks of cars; thus Shelby VINs do not correspond in numerical order to Ford factory VINs.
