64 dart with 4 speed with o/d clutch linkage question

From the first picture, the stud from your z bar and clutch fork tip should be parallel. Otherwise, when you push your clutch in you are trying to twist the fork on the pivot.
It's geometry is just bad, makes it difficult.
Sounds like this set up is one where you just have to do what you gotta do. For the fellow that gave you pictures of his set up, it could use some correction too, but if it works and he is happy, it is what it is. Just my opinion.
Good luck!
