On the LT shocks, how is the seal head held in the bottom of the shock? Is it one where you push the seal head in, then pull the snap ring and pull the seal head out, or is it like a banshee shock that has a snap ring on both side of the seal head that takes special tools and a lot of luck to get it apart without wrecking the seal head? I need to do a fluid change on mine, but just wanted to verify this before I tear something up.
