Why not just slip (a copy of) the master audio file's TC by two frames?
I'm guessing you took the audio recorder's (or at least the audio guy's TC generator's) TC and jammed right to the F3, not to an Ambient Lockit or Denecke syncbox or whatever attached to the cameras. IME, the F3's clock drifts a bit, especially after a power down. F3's don't drift as much as DSLRs or the C300, but not totally solid. Oh well.
I don't know how far along you are in your edit, but if you have a single audio file (and it sounds like you do), and the TC difference is consistent throughout the day, you could make a copy of the audio file and reset the beginning TC metadata by two (or whatever) frames.
If you want to do this before importing the file (and its metadata) into Avid, you could do the TC change with Wave Agent, a free and useful utility app from Sound Devices. Haven't used it with files from non-Sound Devices recorders (such as Zaxcom), but should work with any standard BWF and WAV file.

Then bring into Avid. But I could be misreading something (my more-than-you-need detail is so you can spot where my understanding went awry).
