Got one of mine installed. The other side I'm gonna have to find a right-angle screwdriver to take the OEM coin guide off. I'm also gonna have to remove the "rocker arm" off as it's causing me issues. Coins go thru 2 or 3 times then get hung up on it.
One problem though. The alignment pegs seem to break off pretty easily. It will probably work without them or I might try plastic welding them back on.
Otherwise, these things are super easy to install. Took me all of a couple minutes on the one side. As long as you have the proper tools, you should be able to hammer these things out in 5 minutes or less.
