Mast jack question

I am planning on replacing the rigging of a 40' er with an experimental type of PBO. As the new rigging has no turnbuckles (that experimental ) I need to tension the rig with a hydraulic mast jack and have to convert the (aluminium) mast and mast step.

As I have never seen such a system I would appreciate it if anybody has any pictures or a description of such a system.

TIA,
Arthur

Here are a few pics of a very crude but cheap system we built for an ILC-40 about 10 years ago. We had a solid steel bar through the hole in the mast and then shims under the mast step so we could remove the cylinders and pump when sailing. The cylinders and pump came from DIY-kit for auto body work and the whole setup cost max 200$
