Quoted from bent98:
Hey guys. I installed swinks 4 degree Target Wedges located here: https://www.shapeways.com/product/ULXAHMCWL/stern-pinball-target-wedge-4-degree-twin-pack?optionId=62462025
Installed was simple. FYI You need to purchase (2) 6-32 X 3/4 inches long machine screw to replace the screw on each target.
I try and play tonight to tell you if it made much of a difference.
Thanks for the screw info, I got wedges too but havent gotten around to installing. you just saved me one step, figuring out which screws to buy.
