A word of caution: Depending on how tight your Time Expander sits to the playfield the Cliffy's may make the Time Expander bind up when moving up/down. There are some mods you can do to help with this (installing washers or even filing away the playfield a bit), but it's not always a simple install with these.
I ordered all three but wasn't able to fit them all on. I ended up installing the top flap and edge protectors, and leaving off the entrance protector because of a lack of clearance.
