Yes, you will need to find a '64 or 65 cable shifted 904. Then you have a few options. You can get a B&M adapter flex plate 10239 to mate the internal balanced torque converter to the external balanced 360 engine. You can just use the original torque converter if you use an adapter ring to adapt the larger engine opening to the smaller torque conv front hub. (See E-bay under the seller TorqueFlitePatty.)
OR:
You can also change out the front 3 main components in the 64-65 904 tranny to 68-70 pieces to get the more modern input shaft and pump and mount a later torque converter to the pushbutton 904. Then you can chose whether you want the converter for 360 (externally balanced) or use a converter from a 318 or 340 (internal balance) with the 10239 flex plate. (See summit etc.) The advantage to this is a much more available selection of torque converters. If you're rebuilding the 904 anyway the tranny shop should be able to fix you up with this solution easily.
The cool factor of the pushbutton shift is worth the effort!!
