To remove the siderails, I use a 1.5 inch wide putty knife, drywall knife, a dead-blow hammer, and wide blue masking tape.
Remove the bolt on each rail at the coin door end, and the nail, if so equipped, on the other end. WPC-95s have nails, previous games don't.
Run a bead of blue tape along the bottom of the rail, and then take the drywall knife at an angle, and score the cabinet art *above* the railing. If you put the blade at about a 45 degree angle to the cabinet, you can use the bottom of the rail as a guide. This is important, because if the tape sticks to the sideart and rips sideart, it will be hidden by the rail when reinstalled.
Then, lay the putty knife against the cabinet, blade underneath the rail, and gently tap it with the dead blow hammer until it cuts through the tape.
It's important to use a dead blow hammer, as the hammer is rubberized and won't damage the cabinet if you slip.
Do this from front to back on each rail, and the rail just lifts off. Clean the adhesive off with your solvent of choice, goo gone, orange power, etc.
Apply fresh 3m double faced tape to the rails to reattach. I use the 7/8 inch thick stuff from my local auto parts store, comes in a 15 foot roll. Should be able to get 2 games out of 1 roll. 15 bucks or so per roll.
