Re: 1964 Four Speed Information Thread
One more note on the shifter handle--it has fine thread on the end for the knob to screw onto--later ones had coarse threads.
The bracket that mounts the shifter to the tail housing is 3/16" piece of steel bent and then threaded for the shifter to mount to. The newer ones had a stamped piece that was thiner and looks completely different.
Manual transmission cars had a solid driveshaft tube whereas the automatics had a rubber insert (tube-in-tube) design.
As for the Z-bar, I got some insite into that years ago from the guy I bought my '64 4-speed car from. He bought it new and it had the 3-piece z-bar design. It was cast and actually broke on him. The replacement was an improvement--the one piece design. Apparantly Buick had problems with the 3-piece design and updated the design and sold the new design as replacement part. My '65 Special that I recently sold still had the original 3-piece design on it when I got it. I found a NOS replacement one in kit form (back in 1994) that I put on my '64 when I restored it, so I put the one off my '64 onto the '65. I still have the original 3-piece one off the '65 in the closet at the house. I also have the broken 3-piece one from my '64 that the original owner kept all those years.
The one piece design is superior, plus it has more mechanical advantage due to a longer leg, so it is much easier to press the clutch in with it.
