If the clip is loose on the fork, yes it can make a big difference. The spring on the fork to bellhousing is pulling the fork AGAINST the clutch.  If the clip is tight, the spring is pulling fork AWAY from the clutch 

If your clip is loose, cut off 2 rivets holding clip to fork using Dremel tool with High speed cut-off wheels.  Bend clip so it is straight. Drill the 2 holes to accept Tiny bolts and locknuts. Reassemble clip on fork with small wrenches.  The clip should hold the fork very tight against the pivot clip.

You should get a new Z-Bar since yours was cut and rewelded many times.

Madness,
It is so hard to put that fork back in with the trans in. You can try to do it but you might bend the clip again.   If you can get it on, great! If you have a rolling trans jack, it would be easy to slide it back halfway.
The new throwout bearing holders have some grease in the groove.  I put a little in there if it is dry. I also put a little grease on the fork at the pivot.

Good Luck.

Here is a picture of the spring. It has the short end on the pedal and will only fit one way.  This is how it should look.

What does the over center spring do anyway? I never installed mine. Should I?

70ChallengerRT, that spring helps you push the borg&beck style pressure plates in and also helps return the pedal to the up position so that the throw-out bearing isn't constantly touching the clutch fingers till you push in the clutch.  If your bearing always touched the release fingers it would wear out sooner than later, start making noise, then the trans has to be pulled to replace it.  This is the problem Madness has. His clutch fork isn't pushing his pedal back far enough for the over center spring to take over and pull the throw out bearing off of the fingers. Some people take them out when they install a diapham style pressure plate because the big spring is too strong to allow the clutch to release. They should put a lighter spring somewhere back in the linkage to pull the bearing back.

Madness, My clutch pedal pulls itself up very strongly when the linkage is unhooked since I pulled the pedals off and greased up all of the pivots. Are yours swinging freely and greased up?

i read mclouds instructions agein it says 1/8 -1/4 on the bearing if i put it there im sure it would grind the gears and does not cumm back enough for the ov center to return all the ways the bearing is not tight on pressure plate u can easly turn it with ur fingure maybe this is as good as it gets i started it up can see the bearing spinning maybe that does not mean anything its not tight just seems like there should be more ajustment i will not cut up another z bar pedal are lubed well did that before install all the parts are where they should be and workin right except the ajustment

1/8 to 1/4 inch of gap?  No way.  My pedal would not pull up all the way if I put that much gap between the bearing and the fingers.  Adjust the nut till the bearing comes off of the fingers by a couple of thousands, till the bearing stops spinning with your foot off of the clutch. If the car isn't running, put your hand up inside the bellhousing and spin the bearing with your finger. Loosen the nut till the bearing no longer touches the fingers. A veri small gap is all that is needed. Now when you push in the clutch pedal with your hand, you will feel about 1/2" of play before it gets harder to push.
