I think we've all got 'em. I bought my first pinball earlier this year, and now have a second that's a project machine that I got for cheap to learn on (D&D). My Whirlwind, my first pin, is in almost perfect shape, except for one broken plastic that I can't find a replacement for anywhere. It's the long, thin plastic, just above the yellow NW target, to the left of the upper ramp. I scour everywhere, follow every lead, and can't find it. (So if anyone has one, please PM me! =D)
So that's my piece, what's yours?
