Could go either way -
- ABX have the 76s they bought from Delta without checking that was what DHL wanted. Could be they'll replace the 72 extentions but they've got to go through conversion first and that'll take time.
- DHL want, over time, to move away from the 'C' cans of ABX to grown up 'A' cans so not liable to take more other than the point above.
The only thing you can be sure of is that, one way or another, it'll all change eventually!
