finds no 747 with an incident on that date.
In fact, there is no record of a 744 incident in the US for that year. The only 747 incident listed for SFO
in the 1990-2004 period is this one http://www2.ntsb.gov/ntsb/brief.asp?ev_id=20031122X01939&key=1
. United, but no engine out.
If you can pin down the incident you should find it there, including the reg.
They list non fatal stuff too and this sounds like it should definitely have been investigated by the NTSB.
