<VV> Turbo sealing ring suggestions?

[Grant Young]

As I was finishing up my one hundredth turbocharger rebuild today, it occurred to me that I have burned up at least $500 worth of suppressor rings for the turbine shaft seals. I gave up trying to use the wire tie idea in the shop manual years ago, so I am hoping someone with some experience with these things has a better and cheaper alternative for installing the rings (the suppressors are now over $8 each). This is apparantly a significant problem based on large number of units I have taken apart that were damaged because the sealing ring was not installed properly. Thanks for any tips.
