904 IN A 64 DART - 06/17/15 08:01 PM
VEHICLE IS A 273 904. INSTALLING A GOOD 360 AND 8 3/4 AND TRYING TO DECIDE WETHER TO USE THE 64 904 OR A 70 904. WHICH WOULD YOU USE IF REBUILDING AND CHANGING TO A FLOOR MOUNT SHIFTER. DO VALVE BODIES NEED CHANGED? DRIVESHAFT???

I'd go with the 70 for ease of linkage install etc.

Driveshaft will need changing, valve bodies are not interchangeable between the two. Not gonna find an aftermarket floor mount shifter for the 64 Torqueflite as far as I know.
From an upgrade point of view (torque converters, shifters, etc) the later 904 is a better choice.

I'd go with the 70 & fab a shifter. this'll give you the slip yoke so you would need that yoke & may or may not have to shorten the shaft. Use the '70 TC (cant use the 64 TC with the 70 904) & you wont have to buy the ring for the TC nub needed with the 64 TC/360 crank pilot hole combo (pattys TF's if ever needed iirc). Not aure if '70 has the PTK or not, a desireable feature. HOWEVER just me if I had a 64 pb vehicle and a 64 PB trans I would stick with that, looks neat looks original no added floor shifter which I dont care for their looks/clutter
