I picked a refinery MET premium recently. Only thing I want to change is the coffin block. I've seen shavings of metal on the playfield from it and had to pull the glass to clean off. What's the preferred replacement, just a Newton ball? On some pics I've seen on here, there appears to be some sort of u-shaped bracket holding the captive ball...

Here's a picture from the last page of the bracket.

Thanks! Great game so far, except that my kid (he's 10) has the high score right now (444m).

I found the correct Newton ball on pinball life. I had been looking at the one that is just a ball with a rod sticking out and couldn't figure out the bracket. Found the one with bracket and ordered.

All I could find was the gel inserts for the fuel targets. Maybe you can get sheets of the same material in other colors? https://mezelmods.com/products/metallica-pinball-gel-inserts
