8/30/2010: I contacted Kaman Industrial at 916.372.7812 (a Harwal Distributor in Sacramento, CA) and talked to Franko to order the part.
Price: $58.00 US. Add Tax and shipping. (Note: the non-viton seals were $19.00 US).
Once I get the seal in hand, I will have a chance to compare against the old seal. Will let the group know the results.
