If in the case of an individual who has attained age 62 or died or is under a disability and who has been paid wages for agricultural labor in a calendar year after 1954 and before 1978, the requirements for insured status in subsection (a) or (b) of section 414 of this title, the requirements for entitlement to a computation or recomputation of his primary insurance amount, or the requirements of paragraph (3) of section 416(i) of this title are not met after assignment of quarters of coverage to quarters in such year as provided in clause (iv) of the preceding sentence, but would be met if such quarters of coverage were assigned to different quarters in such year, then such quarters of coverage shall instead be assigned, for purposes only of determining compliance with such requirements, to such different quarters. If, in the case of an individual who did not die prior to January 1, 1955, and who attained age 62 (if a woman) or age 65 (if a man) or died before July 1, 1957, the requirements for insured status in section 414(a)(3) of this title are not met because of his having too few quarters of coverage but would be met if his quarters of coverage in the first calendar year in which he had any covered employment had been determined on the basis of the period during which wages were earned rather than on the basis of the period during which wages were paid (any such wages paid that are reallocated on an earned basis shall not be used in determining quarters of coverage for subsequent calendar years), then upon application filed by the individual or his survivors and satisfactory proof of his record of wages earned being furnished by such individual or his survivors, the quarters of coverage in such calendar year may be determined on the basis of the periods during which wages were earned.
