Quoted from lb1:The left side of the the center ramp entrance got hit pretty bad. The metal had mushroomed. I grinded the whole thing and drilled two holes. Once the ramp comes back from plating I might add some rubber protector.
Stern had released service bulletin 154 to prevent this from happening, looking at your ramp and playfield pictures, it appears this upgrade kit was never installed. http://www.sternpinball.com/upload/downloads/sb154.pdf
The post upgrade kit Pinball Life has is a superior to the one Stern released in the service bulletin, and I would highly recommend getting this. http://www.pinballlife.com/index.php?p=product&id=1045
