I think you'll struggle to find a 4.444:1 ratio CWP for the front diff in a 6 speed as it is a different size to a classic 5 speed box
The final drive pack in a UK 6 speed is also 1.1:1 not 1:1
DCCD was available on the WR1, and then the MY04 Type UK on (when the 115x5 PCD wheels came in, and there were spats stuck on the rear wheelarches)

I can get 4.444 final drives front and rear crown and pinion form Sti Japan,
Tim W: What ecxactly is the "The final drive pack 1.1:1" ?
Do I have to change that also to 1:1?

I thought the 4.44 ratio was for 5 speed gearbox's ??? I thought thats why the cars have moved on from this as it has been proved the feel of the quicker accelerating gearbox isn't as quick as the normal ratio box !!

The final drive is in the centre differential, on UK cars the CWP front and rear are different ratios, to balance them out the final drive is altered.
So if you want 4.444 (which I'm sure are only available for the 5 speed box, not a problem for the rear diffs as they're the same sizes on new age cars) front and rear you need a 1:1 final drive.
UK cars have 3.9:1 front and 3.545:1 rear CWP and need 1.1:1 to balance the ratios

I take it back, they do seem to offer a 4.444 CWP...daft...the ratios are far too low as it is!
TY856WN3CA = MY03 Type UK

MY03?? But it has DCCD. You said that DCCD exists on MY04 on... bloody confusing!
So, it must be 1:1.1?
Where did you find this information from?

I know that TY856WN part denotes UK, but the last three digits missing form the tables denotes the year, that's the confusing thing.

TY856WN3CA is listed on the IWOC link though as MY03 UK without DCCD, but that's only one link
