As DY has pointed out, there is no concrete proof that it ever occurred. (I am not even so sure how much Rav Aaron had with Rav Moshe prior to arriving in America.- If anything it was more likely that either Rav E Silver or Rav A Kalmanovitz was involved with Rav Araron Kotlers arrival).
However, there was the famous Goral haGra performed by Rav Aryeh Levin in Jerusalem by the request of Rav Tzvi Pesach Frank to identify the burial spots of 12 kedoshim who died in 1948 war. Rav Frank relied on it and buried them accordingly.
Just google ר’ אריה לוין גורל הגר”א’ for all the details.
Also, see Rav Shlomo Klugers Psak regarding when we can perform Goral and when not.
