Truth.  All they have to do is match.  Make up your own artwork entirely and only a couple people might ever notice if they match.

I replaced the auto launch on Tommy - now it gets a proper plunge all the way around 95% of the time. I'm confident the few misfires are due to the ball being unsettled in the lane during multiball.  I originally just screwed it in the same as the old assembly and it worked exactly the same as the old one-very weak.  So I took it down to the shop and slotted or enlarged some of the holes to allow more sideways adjustment to line up better with the ball.  That nailed it.  I also moved the shooter rod over to match.  I'm still glad I replaced it because the old one has some super nasty welded repairs on it, and some serious linkage wear. 



The assembly came from Marco with a different coil # than stock.  I reused the old coil which should be the stronger of the two - 600 wraps v/s 800.  A lesson learned- line everything up with the ball where it sits rather than the center of the shooter lane.

I ordered a replacement VUK plastic $13 and some cab touchup paint for $5 from pinball universe, but I'm going to keep the plastic out until I've completely solved the cracking issue. (my recent replacement is already cracked where the ball hits it on VUK exit.)

Crack is right across the guys neck.  you can see how far the plastic goes inside the cage.  I'm going to make a new one with this area scooped out.

    I may have missed the lesson learned....Line it up where the ball sits, not the center of the shooter lane?
         .....Edit..... Oh Jennifer gets it, nevermind.

ChadTower:



Definitely looks like the solution here is changing the shape of the plastic.  Might be worth forgetting about that right most screw entirely and just don't bring the plastic that far over.

ChadTower:



Hrm.  If that were a tolerance issue on the screw holes then the art wouldn't match them.  The pic makes it look like everything is in the right place except the plastic and that can't be right.  Maybe it's the wireform that is supposed to be sticking out further over the hole.  Could the wireform be malformed? 


Is this an issue with all Tommys?  Some games have a plastic or two that are just doomed by design.
