I figure that my worst case is that I split the front stencils apart and try to come close to the original placement. The sides are off a bit, but I can center them and live with it.
At the end of the day, I got the stencils for $60 and I'm definitely going to keep the machine (I'm going to get the CPR playfield, backglass and plastics set and have spent a ton of time finding and cleaning up spare playfield parts -- I'll never get that money back from a sale), so it's not a terrible outcome.
But, with the day I've had, I was really happy to see the Canada Post truck pull up with a delivery for me that wasn't business and not charge me taxes or duty. Then I was crestfallen when I pulled out the stencils and saw that they were obviously too small.
It would be nice if he could do something -- it was a pretty obvious cockup.
