I finally got a chance to tip my theater down a little so I can better see the lower portion of the animations. Its not perfect but its better than it was, anymore and would start to lose the top portion. I ended up raising the rear almost 3/8".
I changed out the plunger for my trap door a few weeks ago. I ended up using a flipper plunger which is a little longer. This shortens the stroke of the trap door opening so it does not hit the wireform above it. I changed out the linkage to an arrow head type.
One thing I didn't see mentioned anywhere (or I missed it somewhere) was the lower pop bumper grinding on the neighboring ball guide. The same issue WOZ had. I needed to grind off some to give a little clearance. Unfortunately I didn't notice this until I had metal shavings all over the playfield. The ball moves fast in the game so it spread pretty quickly. A little late but hopefully this will save someone some trouble.
