Quoted from hawkmoon:
I put new decals on mine,they didn't come on the game,but they went right on without teardown!!
I just got my machine so I am thoroughly cleaning everything and the middle drops needed new decals. I just removed the whole drop target assembly since I wanted to clean it out. Once on the bench, removed the E-clips top and bottom of each target, but at the top watch out for the little spring that will disappear forever if you are not ready for it. The visible spring is the one that pulls it down, the other one is pushing the target forward at the top and is not easily seen while in the machine.
