Thanks for your excellent reply, Robroy!
About the frame-mounted bracket moving around: did it move around even after you torqued it down? I can try to find out the torque setting I used on mine if that would be helpful to you.
I didn´t torque it up yesterday, but I had it pretty tight by hand. Torque rating is abround 40 ft.-lbs., I think. I found it somewhere in the shop manual but can´t find it again right now..
But I don´t think the torque would make a difference, as the bracket wasn´t moving around the bolts in its bolt holes. It was pushing the "wall" of the bracket, where the z-bar is attached to, around. Sorry, don´t know how to explain it better. Maybe I has pushed it too far in direction of the engine and it was getting pressure in the fender direction therefore. I´ll have to try this again.
So, with the info that mine isn´t the only bent z-bar out there, I think I´ll stay with my old one and change the balls and seals.
How did you remove the actual bar from its mounting bracket?
And thanks for all the interesting links! There are some very good ideas there! Gotta check the entire clutch linkage again and see if I need to replace anything else.
