Shocks are not as hard as people think. With that being a remote reservoir, I think it had a Schrader valve. Which makes it quite easy to release pressure and charge once you are done. Get help to take it apart. If the seal head is in reasonable good shape, all you will need is two seals and several o rings. These parts can be ordered through any hydraulic shop. Just might take a week or two. This way is much cheaper than sourcing the parts through a `kit`. Probably under 20 bucks. I did my Ohlins this way over a year ago. Good Luck!
