This guy shows you how to install them. To remove it just do the reverse of it.
Basically you have to desolder the switch corresponding to the stabilizer first. After that you push the "tab" on the north side of the stabilizers (side away from you, push the tab towards you) which unlocks the stabilizer and then you can lift it towards you in a half arc motion.
After that align the stabilizer bar then slide off the middle notch on the plate.
To be honest the annoying part is desoldering, after that removing the stabilizer parts aren't too hard. Let me know if you manage to get it to work.
