Learn me: Rebuilding Fox IFP shocks

I'm piecing together a lift for my land cruiser and have a lead on some cheap used Fox 2.0 IFP shocks. The catch: one is blown. Before I install them I plan to rebuild the set. Fox can do this for $75 each, but I also found you can buy rebuild kits for $10 each which got me thinking about a DIY rebuild.

I have reebuilt motorcycle forks before, and the process for the shocks seems similar, but with the additional step of pressurizing the shock with nitrogen. The Fox shocks use a self sealing rubber valve and are pressurized using a needle like a basketball. There are different needle legnths for different shock models, and I think I will need both the short and long version.

Has anybody rebuilt this type of shock before? Is it as easy as replacing seals, filling with oil and stabbing it with a needle?

Thank you

I've torn other Foxes down for revalving, which should be the same process. After the first one, I got a shock clamp for the vise.  To pull those seals, you'll probably have to pull off the shim stack. Be very careful to put this back on the same way up

Fox feels strongly that you should use Fox fluid, so add that to your cost. It's one of those things that costs a fair bit the first time, but is cheap after that.
