This is the info from another group...
600 racing has notified a number of seal builders East of the
Mississippi of their impending release on Dec 20 2007. Ken Joyce, Curt
Andrews, Larry McBride, Doug Stevens, and Kendirk in FL. Their may be
more, but according to what I was told, these guys were informed via a
phone call from Darrell and a followed up letter. Whatever sealed
engines are in their shop, they are to give the MTR number to 600 and
will recieve seals for that engine to finish. If you don't have your
engine at one of these guys shop, I guess you'll have to sent it to 600
or maybe one of the others not let go yet. Progress or failure, time
will tell.
