This is a twin pack of wedges (enough for 2 standup targets) that goes in between the target bracket and switch to tilt the target forward and greatly reduce the airballs off targets when hit with a powerful shot.
This issue has been a big issue on the Stern Ghostbusters X2 & X3 Multiplier targets either side of the ramp. Whiel a few people have made the air ball protector they effectively trying to control the result and not fix the issue.
This wedge will greatly reduce the air balls and cause less damage to your game.
You will need 1 wedge per target. You will also have to source a slightly longer bolt for the target assembly as there just isn't enough thread once the wedge is installed.
You will need to source a 6/32 gauge x 3/4 long bolt per target as the current 6/32 gauge x 5/8 inch bolt on the thickest part of the wedge is just not long enough.
The attached photos show the install location and where I replced a hex head for a slightly longer same threaded screw.
This is the second version which is 2 x wedges linked with 2 small sprues that you cut off as the sprues allows the price to drop a little due to just one processing charge. There is a small chamfer next to the wedge, simply cut at this point. Buying a twin pack versus 2 x single wedges will save you $2.15 total.
Note (21-4-17): it was one sprue and Shapeways requested for me to add a second purely for the polishing process - the wedge itself has not changed.

I edited a picture that hopefully helps those that need it. I do admit that during the time waiting for refined wedges I installed 1/16" thick white double sided tape (near my thumb) behind the target to firm up the target and reduce the bend back and possible launch of the ball. Then when the wedges came I installed and didn't think to share that minor detail - sorry.
basically 2 install locations
Location 1 - brings the backing plate closer to the switch making it a little more sensitive. Adding the small piece of double sided tape will firm the switch up and reduce the effect of the ball getting airborne. I am playing with this set up and still get the odd minor air ball but not shooting over plastics and lanes etc and the switch is not as sensitive as original so not a given shot.
Location 2 - keeps the switch standard sensitivity but will still allow the target to tilt forward and when hit to bend back to a 90 degree position and possibly allow the ball to get airborne. Adding the tape will firm up and keep the ball / target at less than 90 degrees when hit and should be a improvement on airborne balls.
