Looks great Nino!
Yes, it is hard to get parts for Stern flippers which is a shame, as when they are going properly they are the best feeling flippers from that era (in my opinion 
). I agree that cutting your own bushings to the correct length is the way to go. I was lucky enough to get some NOS Stern coil stops, but before that I was considering changing the hole arrangement on the baseplate to accommodate the easy to find Bally coil stops.
Interesting that your Galaxy has the correct (stronger) 25-450 flipper coil. These are usually changed to the common 25-500 some time over the last 30 years!
Any classic Sterns in your new haul?
cheers

I wish you were local Ian so you could have a few games - it is one of the best Sterns I've done (this is my third Galaxy). I might follow your suggestion when I restore my Flight 2000, as the "old style" Stern coil stops are not an exact fit. If there was no coil sleeve - then it would fit, and I didn't want to bend or modify the base plate unless I had spares. I used to simply remove the Stern hardware, and install Bally hardware - but I would rather use the Stern flipper assy.
No classic Sterns I'm afraid. I missed out on a Viper, which I would have loved !
