Doug,
I have a rockshaft that has already been cut to specs for a hydro lift that you are welcome to and I have an electric lift that has part #19 on that you can measure and adapt (the hydraulic lift one is 3/4" narrower) and I have that cleavis on my electric lift that you can measure as well. Just need to find some time to get together---sorry, doing an entire house remodel and time isn't on my side. PM me after next Wed. and we can try to set up a time.
This is a thread that I posted years ago with some really good help and pics....hope that it helps you also!
