Here's the protector, with the protective film. It is designed to install on top of the existing plastic. The large hole is for the lower post, which would interfere with the ramp if it were to be raised.
Here's the installed protector, over a broken plastic, with a ball against it. The ball can't get to the edge of the protected plastic when flying, and the bumpers keep it off when low. Bottom line, the ball can never touch the plastic.
Next, release the right ramp by removing the obvious screws and nut. You'll need to disconnect the ramp flasher cable. There's no need ot remove the ramp. Cant the ramp so that you can get a screwdriver onto the middle mounting screw. Be careful not to break the plastic arch valance.
Here's the broken plastic with the protector installed. Note that it goes on top of the plastic, rather than underneath. This is because the under ramp post is very close to the ramp, and the screw will touch it if the post is raised. The other post is assembled on top of the protector.
Closeup of the protector installed. It protects fom drops from above, and reinforces against uppercuts from below. Note that the original plastc extends out further than the busted part you see here.
This install took longer than it should have done because two screws were cross-threaded. The head twisted off of one, causing a repair exercise.
I like to replace the star washer screws with cone washer screws. They look better and work better.
