As I understand it, all '65 and '66 GT350 (and I am pretty sure all '67s too including GT500s) were San Jose built cars that carried an "R" in their VINs. They were shipped to Venice Beach and then LAX where they were modded by Shelby American. The '68 Shelbys were all built in Metuchen, N.J. plant and carried a "T" in their VINs, and were modded in Livonia, Michigan at AO Smith.
