I printed and handcut my own, but I believe PinballPimp makes them too. Not sure why he doesn't list them on his site. Pinball Pimp stencils yield a MUCH higher quality than I got with a printout and an x-acto knife, but I was able to make on the fly modifications and additions that felt missing in the art. See if you can spot them.
I obviously also changed the color scheme to better suit the game too.
I bought my Galaxy with intent to convert it to a Quicksilver or Star Gazer, but my dad liked the game so much I wanted to keep it alive. I had a totally wrecked Bally Supersonic in his garage that I used to make this happen. It's not a "collector quality restore" but the game lives on and plays great.
