For the 1970 Gt500 automatics cars: During the 69-to-70 conversion, was the existing "born-with" carb modified...or rather was a replacement carb swapped out in place of the original carb ?
My understanding is the distributor was a swap-out scenario, but I can't seem to specifics on how the carb mod was executed (i.e. carb swap vs. carb mod).
Knowing this would help me determine appropriate date code for my 02/28/69 built 70 GT500 auto. Trying to determine whether to be in the ballpark of a 91_ date versus 97_ date.
Thanks
Adrian
