So at the very least, you are needing a cross shaft (Z-bar), a frame bracket and an engine bracket. Not sure if your pushrods are usable or not. What year is the truck, and was it converted from an automatic or was it a factory stick?

I don't quiet fully understand this. I presume your clutch setup was all factory and in working order when you brought it into the shop for a clutch job?

The z-bar to frame mounting looks right, still rivited right? which makes me wonder: did they foobar the engine side of the z-bar mounting and have to fabricate and weld a "fix" in there while doing a poor job -- and is that what the 2nd picture is of?

Those z-bars are pretty tough stuff. About the only thing that wears are the holes where the push rods connect. In each end are ball studs so you can run it with the angles you have; but sounds like maybe the push rods then bind.

I would check that the z-bar mounting on the engine block is not flipped backwards giving causing the ball stud to be to far forward/backwards.

I just don't get what they would have to fabricate in there.... or why.
