Well, I don't know which version you have, skyjedi but my R1 DVD of American Graffiti have a dolby 2.0 surround track not a 5.1 track. I know the audio was in Dolby for the first time in '78, it even says so on the posters of the re-release but are you sure the initial '73 release was in mono? I thought they just reworked the original 4-track stereo into Dolby because it was the new popular format back then.
You are right the DVD is in 2.0 and probably is the theatrical audio, from the re-release if you discount the bad new color job and cgi you could pretend it is the real version of the film.
As for Graffiti i now for a fact some prints were in mono, even if it was mixed in stereo. Lucas insisted all prints be stereo but the studio did not want that as a lot of theaters at the time were mono equipped and the studios thought stereo was a gimmick. I think it was in an old Lucas interview from the late 60's but again i am relying on memory.
