Syncing 23.98fps timeline with composers 24fps files?

I have sent 23.98 QuickTimes to my composer, who is using Logic Pro, and is only able to work in 24fps. When he returned a test audio stem ("our" audio, after running it through Logic Pro), and we dropped it into our timeline, it was of course out of phase from the beginning and the sync gradually grew worse during the three minute clip. At the end of the clip, it was 6 or 7 frames out, with the audio ahead of picture.
Is this something we're doing wrong on our end, or does he need to do something else? And is there a process we can try after we get his files back?
G5 Duad, FCPro Crossgrade (current), DVCPro 50 sequence, Orignal DVCPRO50 video material shot 24PA, run through Cinema Tools to get 23.98 material, WAV audio files coming back from composer

He needs to PULLDOWN the audio on his end. Logic is more a music tool in this sense. He needs to see if his program can pulldown his final audio.
But, take the audio file in your system, go to MODIFY/SPEED/ and change the audio clip to 99.9 percent instead of 100.
Your audio will now be in sync throughout.
Using FCP to change the speed isn't as good as having say PROTOOLS pulldown this audio to this speed change which is the usual processing. I can't answer for logic and it's full interworkings - I know people that have used it for 29.97 shows..but that's it, I hear this 24fps ONLY often though.

[The Edit Doctor]"But, take the audio file in your system, go to MODIFY/SPEED/ and change the audio clip to 99.9 percent instead of 100."
You can do this, but it's not exact.
To be EXACT, the best thing to do is open it up in Cinema Tools. Must be video and audio since CT can't do audio only for some reason (you can of course separate the audio after the fact if you need to).
Just use the "conform" option. Bam. 23.98 is converted to 24 instantly.
