Bulkhead Drain Channel / Bonnet seal for 1984 90

Hi
I have a 1984 90 and am looking to replace the rubber seal between the top of the bonnet and the bulkhead drain channel. I can find replacement seals (LR053843) but they all seem to be for models with VIN numbers after DA438754. My VIN is AAxxxxxxx so I am unsure if this part will fit
Any comments, feedback, suggestions much appreciated

Same seal for all Land Rovers 1983 to 2016 as far as I know.
