Overdrive 4 speed linkage

Oh man. I've had this exact problem in my '65 Barracuda after I installed a 360 and the A833 overdrive gearbox with the aluminum 10.5" bell housing. I'm stunned that nobody ever put together the exact right list of bits necessary to make it easy to use. Tons of comments from the usual sellers like "oh, that should work. I guess."

I've had every clutch fork and z-bar combo and tried to make them work. It was always incredibly hard to depress the clutch pedal. I finally went hydraulic and fabbed up a small plate on the firewall to hold a Wilwood master cylinder and then an internal throwout bearing. The hard part is aligning the height of the master cylinder pushrod to bolt to the clutch pedal in exactly the right place. Mine is still too firm, but only half the foot pressure necessary for the best I ever got with a z-bar.

I'm not saying I did it all correctly. But I did spend tons of time and money trying to make it all work with stock or stock-ish parts and finally got fed up. I'd prefer to use an external slave cylinder just in case the internal throwout bearing fails but until recently I didn't have the room because of the headers.

It would be great if someone sold a proper kit or at least a parts list and some measurements of what to make. After all these decades it's still a total PITA.

I dislike automatics but my stupid adventures with all this really make me consider cutting up the tunnel and installing a GM 200-4R.
