Quoted from little-italy:There's no wear under the side rails. I put them on all my Sega's. The price includes the extra parts too. Thanks
No wear, But the screws are put in the lollipop rails ouch, Should have left those out, They do just fine without the screws installed. Maybe turn the machine on and then take pictures of it, For 4k the machine should be on in your for sale ad pics.
