Jeff, for your info, this marking is from 6S1640, this is the '66 Shelby that you saw up on the trailer at SAAC 35 last year at Infineon Raceway. Glenn
PS - I'm still in process to get the drive train fully functional, but taking time to document all markings the best that I can, including tracings as I restore the drive train. Unfortunately the front carrier was replaced with a '68 date coded gearset. Eventually I will get the correct 65 date code and replace, but for now, I am simply excited to get this beast running properly.
