Why are these two throwout bearings so different? The tall one is (I believe) the part number recommended in Gary68s transmission LS swap thread.
The short one is what I had in there for the ZZ502.
I currently have the short one installed, because I couldn't see why I'd want such a differently sized one - it has to throw something off somewhere, and I'm basically trying to duplicate the dimensions I had for the ZZ502.
Is there a reason it's so much taller? Should I somehow make it work, or stick with the short one from the previous setup?

You need to measure your set up.
Google "measure throw out bearing depth"and watch a video/start reading.
I didn't measure mine the first time through because I stupidly trusted the vendor who sold it to me. Overextended the HTOB and had to buy a new one.

Is that distinctly different from the fork angle setup? Because that appears spot on.
I have yet to find a reference that shows setting up a mechanical linkage throwout bearing, but I'll keep looking.

Re-read my post. The longer bearing is for the 0.4" shallower 98-02 f body LS1 flywheel. The shorter is for the thicker Sachs flywheel. When combined with the adjustable stud, you can get correct geometry for your fork.
"Throwout bearing: The thicker Sachs flywheel will work with the old 1.25" throwout bearing, clutch fork, and pivot ball. An adjustable pivot ball is always a good idea, and here's a good site for clutch for geometry.

And the shallower LS1 flywheel will require a longer, about 1 3/4", GM throwout bearing (PT614037)."
