<VV> Rings

[Dave Morris]

All I can say about the Grant oil ring specifically is this, don't try to 
use your ring expander to stretch it wide enough to slip over the other 2 
installed rings.  It will snap and you'll be trying to find someone to sell 
you just the one ring.  Trust me... don't ask how I know.
