Lost curl control on the loader, and then noticed I had a decent leak at the raise/lower valve. Not spraying but definitely seeping at a decent rate.

What is the repair process here, clearly I need the "seal plate", but should I plan to also get the spool seal kit?

Looks like a bunch of o-rings under that seal plate/spacer are labeled 'D', which looks to correspond to the seal kit 300, if I'm reading this diagram right?

Yes that's the seal kit you need, I would get the other seal kit and do both spools while your in there.

Yeah, it definitely doesn't look like a bad plan to do both. Any resources on doing the seal replacements? just pop the top off and swap things?

Yea just clean it all up really good, I use orange cleaner to get the heavy stuff then use brake parts cleaner to finish it off.

If the detents feel sloppy you could do that too while you're in there.

I think they are pretty easy to work on, if you have an issues along the way just ask.
