Hurst Competition Plus shifter kits are made for a correct fit in a particular car with relation to the floor tunnel and seat type. The only problem you may have is in 64 GM didn't use the 4 speed Saginaw. Only Muncies were available at that time. So ordering a Competition Plus for a 64 Chevelle with a Saginaw and bench seat will get you nowhere. Now the good news.... The shifter mounts on the Saginaw in the same location on the tailshaft housing as it does on the Muncie BUT you can't order a Muncie shifter as the linkage rods won't be even close to what the Saginaw should have. Order a Hurst Competition Plus for a later model Chevelle / Malibu with a Saginaw 4 speed and bench seat and you should be ok. Worst case is the bend in the shift handle will not clear and since it bolts onto the shifter you have about 30 to choose from the Hurst catalog with different heights and bends.
The Competition Plus keeps all the linkage and most of the shifter itself under the floor. The Hurst Indy universal 4 speed shifter does not and ends up being a sloppier looking install and might require a big added hump on the floor of some cars.
