Copper washer transfer Case

Can anyone tell me what size copper washer I need for the drain plug on the transfer box casing of my Range Rover L322 2004 3.0l td6 vogue.

Don't have a clue, if it's weeping knock plug back and nip up see what you get. If you are changing the oil anneal it by heating to cherry red and allowing to cool.

That is oil this is the washer. https://rimmerbros.com/Item--i-IYF500030

Oil comes up as IYK500010 according to Rimmers
But yes, LR cat shows two transfer cases so I may have picked the wrong one
IYF500010 on one & the other IYF500030. Both of which come up as copper washers on other suspects incl Craddocks so I don't know why Rimmers goes to the oil.
If it's any help Britcar show pics of both against a ruler.

Thanks guys
