Removing the side rails is pretty easy. After removing the flipper buttons, you will find one bolt at the front of the machine for each side rail. After it is removed you will need to pry off the side rails.... Something broad and thin is gently driven up under the side rail. I have a unique little crow bar that I use. Just start at one end and gently pry the side rail. The nails come out pretty easily and can be reused.
