hard top sealing rubber

Has anyone on the list figured out an acceptable JC Whitney part number for
the rubber top-to-deck seal for a factory bugeye hardtop?  I've been able to
find correct replacement window channels for a Morris Traveller from JC
Whitney and saved about 50% over MM prices.  I should think most of the
overpriced rubber bits will have an equivalent if you can figure it out from
the tiny pictures in the catalogue.
