Tym t273 remote hydraulics

[Jeepman33]

Im looking to add remote hydraulics to my t273, after looking online at diagrams there is a spool underneath the driver seat with a lever sticking between your legs, I guess this was an add on option. Does anyone have a part number that is on the actual valve, or the vavle faceplate? I found tye TYM part number but can't locate a valve for sale.

Thank you,
Jason
