I wonder if the shims on the compression valve have weakened to where there isn't enough damping and the rebound piston is just slamming in to the compression piston in the cartridge.

A friend of a friend who is an experienced tech came back with something pretty much like you said. He asked if I do a lot of wheelies, LOL. I don't know what they guy who put the first 10K on it rode like.
I've been watching fork rebuild videos all afternoon...

I'm looking at this diagram and I don't see a valve. I'm trying to figure out what parts might be bad.
On the left side fork, at the bottom right of the picture, is the cartridge. Inside the bottom part of that cartridge is the damping valves:
At the very bottom is the compression valving which uses shims that flex to open the compression valve when pressure is applied to the top piston. If the spring or shims are damaged then there could be no limitation on the flow of oil to the valve and the rebound piston is just slamming in to the check valve.

The detail on the cartridge fork on the right side of the diagram in post #27 only applies to Switchback models. Unless I'm really missing something here, the 2014 Low Rider doesn't have a cartridge in either fork (if it's stock). Both sides use a conventional damper rod design. Super simplistically, the spring supports the weight of the bike and the fluid controls damping. No shim stacks or real valving (although aftermarket emulators can perform a similar function).

This is what it looks like to me as well.
I am looking at these: Progressive Monotube Fork Cartridge Kit - 31-2519
What I'm trying to figure out is if installing these will solve my issues of nose dive and clicking noise. The instructions show only a couple minor stock parts inside the fork tubes are reused - a bottom cup #17 (lower stop) and a small rebound spring #4. I've never done front fork work before, but these have good reviews and look pretty easy to install.
