trying to find SCA file that contains pagetoolbar and masthead par

I am trying to find which SCA file ultimately contains the par files:

com.sap.portal.navigation.masthead,par and

comp.sap.portal.navigation.pagetoolbar.par

I have found apintergtaor in EPPSERV par, but cannot locate correct SCA for these.

( Iwas thinking maybe EPBC ot EPBC2, but not sure if this is correct)
