That works most of the time, but I just had a similar problem. I had put a 5-speed FW in a frame with 126mm spacing (the pink Torpado recently on eBay). I ran the outer stop screw on the Galli RD all the way in, but it still allowed the chain to come out too far and jump off the small cog. Using a 6-speed FW instead solved the problem, but the spacers would have worked also. I'm assumimg it's the same problem here.

Why not just use the outer adjustment screw on the rear derailleur to match the outer limit with the smallest cog? Is the concern that the chain will jump off and jam between the freewheel and the frame? Is it a chainline issue? Lou Deeter, Orlando FL

The aluminum shims are nice and lite, but it's very important that the tightening procedure is accurate and lucky, so that the spacer does not distort and stretch out of place giving an uneven seat.
John is right on the SA spacers. Even better are the Campy steel spacers, which I think came in 1,1.5, and 2 mm. Chose your best chainline width and play.
Even these had to be tightened slowly and without jerking to insure a seating of equal dimension and pressure. Dillitants who slap and ram stuff together either are very unhappy when things fail, or have very unhappy clients short of commitimg mayhem returning to the scene of the crime for satisfaction after the dastardly deed was perpretated on their pride and joy
