sloppy Z bar linkage.....probably pilot error

The TO-fork in the window, should be almost all the way towards the rad with foot off the clutch,

Should read;
The TO-fork,
in the window,
should be almost all the way towards the rad-side ( the front side,or clutch side,or left if viewing it from the driver's side of the car)
of the window,
as opposed to the transmission side, or rear bumper side,
with foot off the clutch.

This is the push rod from bottom of Z Barr but similar play in two spots on both ends of the rod through for wall off pedal

As for the long slots, they have to be there to get over the pins, and the linkage is engineered to work with them, they'll be fine.

The Z-bar has to be positively located so it cannot move laterally. It should be parallel to the ground and at about 90* to the centerline of the car.

If you get this right, it should all work out right.
