The '309 bell is the right one,the hole is large enough to accept the 4 speed and has the throw out arm at 7 oclock position. Earlier bell, the one (before 4 speeds) is for 3 speed part#3788383. It has about a 5/8 inches smaller hole.

Was the smaller hole 63 only like a full size Chevy, Cdn Pontiac, and Corvette? Would Nova/Acadian 4 speeds not be the same as other 4 speeds? Did all 62 up come with a 4 speed as an option?

The '309 bellhousingl is unique to the Acadian and Nova as the throw out arm hole is at the 7 o'clock position. The other bell housings in the GM line won't work for these cars because of this position , but will work for '68 on. It looks like a 4 speed became available in 1964 with the option of the 283 V8 in Novas and Acadians as per my master manual. The '309 bellhousing is found in 6 cylinder cars as well as V8 cars due to the same bolt pattern on the engine block.

Yes, the bellhousing you need would be found in any 64-67 Nova, regardless of whether it's a 6 cyl or V8 and regardless of whether it's from a 3 speed or 4 speed.

So the 7 o'clock position meant it has an "unusual" set of clutch linkage? I assume the z bar still swings off the same place in the block?

Yes the Z bar is unique and has a couple of curves and attaches the same as long as you are using a Nova or Acadian block. If not you have to get a block bracket for non Nova/Acadian blocks.
Yes, the Nova/Acadian block has a unique mounting location for the z-bar pivot ball. Beware that bracket is not a perfect solution either. At least the one I tried years ago wasn't. It fit like crap. It pushed the Z-bar too far out towards the inner fender. The only way I could get the z-bar to fit was to take the bracket at the other end of the z-bar and flip it around which mounts it farther from the block. And when you do that, then the geometry of the clutch pedal pushrod is altered.

Design was oddball from the get go, they should have done the car the way they did every other GM in these years, and designed the car around it. I assume it was a frame or body shape that caused the unique BH, Zbar, block, etc. Imagine the additional cost in designing and moulds for all these changes. Sounds more like what Chrysler or Ford were doing with minor changes almost every year. Now every car maker does multiple changes and you need a VIN to order a car part. Huge costs for insignificant changes.
