clutch z-bar and linkage angle

[warren57]

Installed my z-bar and the upper linkage fit perfectly, the bellousing bracket and pivot stud fit just right. But the angle from the z-bar to the clutch fork is pretty steep. It has to be pretty close to stock, as everything lined up with no issues. It looks like there is a lot of downward push while compressing the clutch fork. Seems it would be better with an offset linkage rod or modification to the z-bar to allow for a lower angle of attack. I realize as the z-bar arm goes back, it also goes lower as it reaches it's lowest point 90 degrees below the shaft, but that is still an inch or more higher than the clutch fork centerline. My concern is the clutch fork with the pin design has horizontal movement ability but is fairly solid vertically. The newer style ball connection rod allows movement in all directions, but the 57 pin through rod shaft limits that movement. If it is similar to stock, I guess it's worked for over 50 years and who am I to say it needs a fix... What are you thoughts? Note the second pic shows a straight in line approach. (about 1 1/2" lower)
Thanks

To me, it looks like the ball is too high on the engine side, especially in the picture taken from the rear (#3).

Warren, as you know I posted a couple of times on your similar thread on the other site.

Chevynut's point that the pivot ball is too high is worthy of noting. I had not commented about that previosly because I didn't see anything out of the ordinary in your photos. One problem you'd have if you lowered the z-bar is that it would require elongating the hole in the firewall for the upper clutch linkage rod. As I recall that was discussed.

Again I think you should at least take this to the point where you find out whether you have a functional problem vs. something that "might" be one.

It's the camera angle, both balls are within 1/8" if you are looking at them without a tilt. Couldn't get the camera in to get a good pic. The z-bar lines up well, pivots well. I think it's fine. I'll know soon, doing a little work to the header on tht side and going to go see chevynut next week and pick up a stock driveshaft. Getting a little closer every day....

Well, with the previous rod angle the clutch pushed in, but not smoothly. Felt like things were binding, jerky like rough spots.
So here's where I ended up. Pushes in smoothly, appears to be what I needed and very quick modification. Measured stroke and have slightly more than the previous hook-up but plenty of adjustment both directions.

Warren, where did you get the bracket bolted to the bellhousing? I'm also in the process of fitting my 55 with the clutch linkage
