I have a 646 that leaks badly from the lift side of the control valve. I'm about to pull the valve and attempt to fix the leak.

I have downloaded and read the valve service manual from the technical library here and have the general idea of what I'm doing once it's out. Still there are a few questions

Can I use any orings in the rebuild? Do they have to be special ordered case or can I just use off the shelf rings from napa or a hydraulics shop?

Does anyone have any tips or advice for removing the valve? I'm planning on following the steps: Drain, Remove Linkage, Remove lines, Remove valve. Any avoidable gotchas along the way?
