Quoted from Jimmyhonda:
Hello everyone, I just installed Game Blades on my Whirlwind. I HIGHLY suggest you use the Soapy water spray method, ESPECIALLY on system 11 games with very minimal side clearance. Just put a drop of soap in a spray bottle with water and spray the back of the Game Blade. With the playfield up, slide the Game Blade into position. The soapy water allows you to readjust over and over until you get it into position. Make sure you you spray it quite a bit because if it drys on you, it’s tougher to adjust. Honestly, this method was very easy with minimal water drips. I recommend it for all game Installs. Just wipe up any water drips with a towel and your done.
