I purchased my 64 Mustang last fall and have just gotten around to checking out the mechanical side of the vehicle and have found that the shifter linkage rod that I have for a 1964 Mustang does not reach from the transmission to the shifter. I know the linkage bar is correct, but not sure what this means about the transmission. The engine is not original so I assume the transmission is not either. The vehicle has the 170ci with the C4 transmission. I was told the engine came out of a Falcon, but am not 100% sure. Do I need more than the linkage rod to connect the shifter to the transmission? Do I need an aftermarket shifter instead of the original? Or is this a different C4 transmission and I need to do something else? Thanks for any help
