Ghostbusters Target Wedges
 Finally got the parts back and did some final testing for a solution to the air balls off the X2 & X3 targets on the Ghostbusters pinball.
 Basically the Stern targets are dead vertical and when hit bend back beyond the vertical which then allows the ball to go into the air. Bally / WMS targets leaned forward, so I devised a simple wedge that can be inserted into the existing Stern target assembly. This wedge now leans the target 4 degress forward from vertical and has been effective in stopping the massive airballs. I still get the random minor ball hop but has improved the design of the target and decreased the problem alot. You will need 1 wedge per target. You will also have to source 1 x 1/8" longer bolt for the target assembly as there just isn't enough thread once the wedge is installed.
