I recently replaced the CA Hinges on the GP Super Sportster 60 you see in my avatar. I just used a hobby knife to slice them free, top and bottom on both surfaces and pulled them out. Yes I took out a "little" wood that was still hanging on, but most were easy enough to pull out. Mian thing is be careful with the knife and not cut and an angle into the wood if possible. I replaced with GP nylon hinges and they fit very well.
