If the diff' is an R180, it's from a Jap TypeR, and won't work.
Fistly, the R180 uses different drive shafts to the standard R160 diff', and the rear wheel hubs/brakes would also need to be changed.
Next, the UK box will have a 3.9 crown wheel and pinion, and the output shaft is a 1.1:1. The R180 is a 4.444, and if used with the 3.9, will trash the centre diff, because the front wheels will turn at a different speed to the rear.
The easiest solution, is to get a UK rear diff'.
