z bar and clutch pedal linkage

Sorry if this is a repeat question, I'm new here and haven't made it through all the old posts. I just bought a '68 Barracuda, with a 318 out of a '74 satelite and an 833 4 spd. ( I was told ) The pedals are out of a dart. My question is can you move the z bar on the shaft? I need it to move over about 1/2". This would line up the bar pin with the pin on the pedal, in the middle of the hole, plus move the lower end away from the stater. I believe its the right z bar, though it only measures 7". I was told it all came out of the same car. Thanks Jon
