need a 904 from a floor shift car

If this is for the '65 that you referred to in your other post, be aware that you'll need a driveshaft and speedo drive from a '66 (to replace your '65 ball & trunnion shaft and 1 piece speedo cable).
Also know that the late ('68 and later) torque convertors will not fit '67 and earlier crankshaft flanges.

I already have a slip yoke drive shaft and a lokar kick down cable installed. The end of the tail shaft I have now is a flat round flange the tail shaft just bolts flat onto the drive shaft and the slip yoke part slide on the rear end.
