<VV> viton crank seals

[lonwall@corvairunderground.com]

Kevin - What brands? Did you have leak problems with any of mine? There 
are (have been) Poly seals out there with incorrect internal seal 
diameters.  The material the seals are made of is not the only factor. 
Also your comments about surface prep is very important as well. Some 
hubs may not even be seal-able no matter what you use. In those cases 
use a redi-sleeve.
