This subsection as in effect in December 1978 shall continue to apply to the recomputation of a primary insurance amount computed under subsection (a) or (d) as in effect (without regard to the table in subsection (a)) in that month, and, where appropriate, under subsection (d) as in effect in December 1977, including a primary insurance amount computed under any such subsection whose operation is modified as a result of the amendments made by section 5117 of the Omnibus Budget Reconciliation Act of 1990. For purposes of recomputing a primary insurance amount determined under subsection (a) or (d) (as so in effect) in the case of an individual to whom those subsections apply by reason of subsection (a)(4)(B) as in effect after December 1978, no remuneration shall be taken into account for the year in which the individual initially became eligible for an old-age or disability insurance benefit or died, or for any year thereafter, and (effective January 1982) the recomputation shall be modified by the application of subsection (a)(6) where applicable.
