Quick Question - Final drive ratio on a MY99 UK classic

For a UK spec MY99 classic
It will have an R160
Is it 3.9 or 4.4?

I know a MY98 UK has a 3.9
I know a MY99 STI has a 4.4

Thanks chaps

on a UK car the front diff is 3.9, centre drop gear is 1.1 to 1 and hence rear diff ratio is 3.54.............
