Thanks to Eric's lead - progress!

I talked to SKF today and they have about 50 of these seals in stock in the
U.S (mainly in Hebron, KY.  They won't sell direct but provided contact
information for a local distributor.  I have ordered 20 which should arrive
in Vancouver B.C. sometime next week.  5 are spoken for and, once the O
rings arrive, I should have enough parts for 7 kits.  In case anyone wants
to do the same on the US side of the border, the O ring sizes on their way

one 7x1.5 BN70
two 18x2 BN70
one 21x3 BN70
one 38x3 BN70

O ring vendor in Ontario is www.globalrubber.com but there will be US


PS The moral of the story - never throw out the box!!
