Z bar alignment

The first pic in post #22
seems to show the plate pulled away from the apron and a crack in the sheet metal. That plate should have been welded on.
I would remove it, and inspect the apron. Make repairs as necessary. If the car was changed to be a manual, you will have to verify that they put the anchor hole in the right spot. This has already been mentioned,and ways to do it, as well.You may have to move the hole. Then when you get that engineered, you can weld the plate back on where it belongs. Don't go crazy on the welding;three or four generous tacks should do it.You cannot depend on the ball-stud/nut torque to keep it in place.The plate has to to be well anchored to good metal, on the apron,especially in the for/aft direction.
Then you can shift the Z-bar transversely, to center the down rod. And finally shim the ball-studs to put them in the right place. That procedure is tricky,cuz the plastic bushings are designed to anchor the Z-bar in place, with a metal-wire clip. At least one end has to be anchored. The other end on mine had a little roll pin which also indexed into the bushing groove.
So that will keep you busy for a few hours.

BTW; nice camera work.We are all here to help.Each of us seems to have a particular skill, and many are overlapping.I'm still a newbe here.
