4 speed linkage woes.

Well I have 2 different Z Bar Photos.
One is a remake that came with my Trans and does not look quite the same as the supposed original.
The arm is longer that goes to the shift fork on the one that is suppose to be stock. and the clocking is also different.
Anyone know which is which? I have a 68 Barracuda smallblock car stock SB K Member and shcumacher stock 318,340,360 motor mounts..
I just completed the install, clutch adjustment was a problem with the newer of the 2 I was told I need .060 between the disk and flywheel the pedal 1" from the floor and .060 between the throw out bearing and the fingers on the pressure plate pedal up.
Also is it correct that the Z bar sits on a slight angel from the engine to the firewall? It seems to be perpendicular to the frame but is angled from floor to hood.
And on top of that should I extend the z bar arm 3/4" that goes to the adjustment rod and moves the shift fork to make the .060 adjustment easier by extending pedal travel?
