71 A230 into 65 Dart z bar/linkage
I have started cutting and making my own clutch forks and Z bars out of cheap swap meet stuff.
If you are skilled with the welder, and understand the basic geometry of clutch pedal/linkage/fork actuation you can do anything you think up. I say it's pretty easy, and I am not a smart person.
The factory Pre '67 Z bars tend to fail on me anyway so I have beefed all of them up to prevent a failure on 45+ year-old parts at an inconvenient time since I drive my stuff a lot.
Good luck!
