td4 gearbox sealing washers

Hello...Can anyone please advise the part number of the TD4 (2004) manual gearbox drain plug & filler plug sealing washers. I guess these are a copper washer type.
I am gearing up to change all my transmission fluids with fully synthetic and at the cost of this stuff dont want to chance the old washers - not for the sake of a couple of quid.
I did contact my local LR dealer, but they advised it does not have a drain plug and syphon through the filler. I think chocolate fireguards come to mind here. Least if I am armed with the part number they can then order the washers for me.
I believe the IRD filler washer is TFY101060 & the IRD drain washer is TFY101070.

I am new to this site and was advised best to ask in the safety of this section ?!

Hope someone can advise, thanks David.

you will find they are similar do a doughty washer.
my td4 gearbox had an alloy plug with an integral green rubber washer impregnated into it. should be good to use again-I did with no problems

p.s I'd stick with the MTF94 in the manual box... IMOH
