You can make the standard push/pull cable operated trans work with an aftermarket shifter, but youll have to remove all the detents in the aftermarket shifter as they are most likely not in "sync" with the detents in the valve body "comb" And youll still lack the second cable for the Park pawl. ISo let me get this straight: You got a 65 floor shifter with 2 cables running out of it, and you have a 64(?) push button or column shift trans? Check out "imperial services" website. I believe they have a conversion kit for these transmissions, but my opinion would be to get a proper 65 cable trans (there is one for 100 bucks listed somewhere) or upgrade to a 66 or newer 904 and a Hurst Pro-Matic 2 as it fits right in the original console and looks stock if it were not for the Labeled ball. This will require a 66 driveshaft or yours modified to a slip yolk of the newer transmissions. driveline shops can do this for under a 100 bucks if you can source them the slip yolk.
