I still appreciate it. I should be able to figure it out now. I wonder where the 1 1/4" goes? That one isn't even listed in the manual.
[EDIT] Using the sizes off the bag you ordered from bestofpinball.de I tried a few of the rings in different spots around the playfield. I tried a 1 1/2" rubber around C. It fit, but it was sloppy and I didn't think it fit snuggly enough. I replaced it with a 1 1/4" I hand in my tool kit and this to me was perfect.
The 2" fit the slingshots.
I put a 1 1/2" around the two star post above the right pop bumper (I mislabeled it 1 3/4").
The 3/4" I placed between the 2 pop bumpers on the left. The 2nd 3/4" rubber is supposed to fit on the two star post just below the left most rollover switch at the top, but there's no way 3/4" will fit there. I measured the old crusty one that was originally installed and it measured 1". Here's where I think everything should go and the proper sizing;

The 2 1/2" rings I believe will be too smooshy. 2" in these locations will be a better fit.
