There's an early built 1970 440-6 RoadRunner convert 4 spd dana in upstate NY that is off the radar I believe.
It has a period dated 1970 440-6 motor and 4 speed and original 4:10 dana still present in car.
Has fender tag, no sheet , but original window sticker was found in owners manual in glove box
The owner contacted GG some years ago regarding the car,
telling him he has the original window sticker with all the codes and their description but no prices for the options in that column.
GG told him that because of the early build those prices had likely not been finalized yet.
It is an F4 car , new white interior and new white top ready to be installed,.. car currently in primer .
