But- adding spools is easy. You need to determine if it's an open or
closed center valve system.
Then you buy the correct type of valves and connect the inlet ports to
the pressure feed. The outputs go to the new quick disconnect fittings
you will need to add.

its easy if you got open center (hydraulic pump always runs) not so
much if closed center. You have an older truck? Pretty sure it would
be open center. If so "T" off your hydraulic line on both pressure
side and drain, add in your valves. FWIW, the Farm and Fleet store
stock this stuff cheap. Maybe they don't have those inside the windy
city.

Ya, you'll loose some lift capacity, but you're starting from 30K

should work well for your needs.
