Are you saying you have a DCCD gearbox with 4.4 diffs front and rear, and have a UK 2004 gearbox that has a 3.9 front, 1.1:1 drops gears and a 3.54 reear diff?

You want to keep the DCCD and use the longer gearing?

If that is correct then swap the centre diff and transfer case over, then rebuild one of your diffs with a 3.9 CWP from a sport, assuming both rear diffs are r160s.

Ah I see, then you can't do that since the rear is a 3.54 and the front from the 2004 is a 3.9. - your DCCD is 1:1 so the ratios won't match up. I'm not sure if the front diffs from a 752 and a 754 box are interchangable anyway?
