where to find NBLU_7.x.x.x.UNIX_1of3.zip files?

NBU 7.6.0.3, Windows 2008 R2 and Solaris 10 clients

i'm following this link to configure my LiveUpdate server http://www.symantec.com/business/support/index?page=content&id=TECH211022 and i got stuck in step 2.3, where it says to extract the contents of some NBLU_7.x.x.x.UNIX_1ofx files.

the only place where i can found NBLU files are in https://fileconnect.symantec.com and i have already downloaded them (2 of them). when expanded, it doesn't contain the files for the Solaris clients (there are 3 files in tar format that needs to be "cat" together to a single file).

appreciate help on where to find the missing files for Solaris SPARC clients.
