Z bar alignment
Everybody is right but I'd like to add; Make sure your engine mounts are not broken,and that the tail of the tranny is where it's supposed to be.
I'd also like to add that;
The installed Zbar has to be parallel to an imaginary line drawn exactly at 90* to the vehicle centerline,from front to back. Any deviation more than maybe a couple of degrees and it will want to spit that special clip off. Now if you have a stout anti-rattle spring on there the linkage might stay together for a while, But it could pop off at the worst moment.
I have seen maybe three different inner ball-stud brackets, that move the inner pivot this way and that. But that matters not a bit if you have a Lakewood, cuz as far as I recall, it has just one integral mounting strap, for the stud.( I mightof seen one with 2 holes;not sure)
You may have to fabricate a new inner mount,or move the outer mount. If you move either one,you may have to re-engineer the levers as well.
Unless of course one of the mounts slipped or it spit out a bushing, or broke the ball off.
