The pluperfect: había hecho
For “had done”, use the imperfect of haber + participle. It marks an action completed before another past moment, and works the same way in Spain and Latin America.
Ya, todavía no, alguna vez, nunca
Certain time words link the past to now, so they usually come with the perfect (in Spain and in much of Latin America). Learn them with a sentence each.
Lo he visto, never he lo visto
