Many of the cables are standard morse cables. I never figured out how to ID the different series though.
On a Kubota M108S I replaced a jury rigged setup using components from Buyers Products.
I used their B206305 dual axis joystick.
I mounted the joystick then measured and bought the cables.
Buyers Products Remote Valve Control Cable features a RVC Adapter Input with a Bonnet output.

For simplicity I bought it all off Amazon. I did have to drill the bulkhead holes out larger on the loader valve mount for the bulkhead mounting of the cable sheath. The Buyers cable have 1/4"-28 threads on the cable/rod and 3/4"-16 on the sheath. If you remove your cable and do some measurements you can see if it would work or not. If not they sell a few cable connection kits that might work.
Hope this helps!
I do not like the valve in the cab as it makes the cab darned hot and its louder. The cables are a pain and require maintenance, but are much nicer in my opinion.
