Westy rear closet door question

[Cali_bay]

Is there different sizes for the rear closet door on a Westy (linen closet)?

I bought one (in good condition) to replace mine as I had a crack in the vaneer, but when I went to fit is it was a bit too small. The size of it is 490x310mm to the inside edge of the cream seal.

So my question is what year is this from? :? :? :? :?

Thanks,

Si

Please could someone measure the following years linen closet doors apertures for me, to see if there is any difference.
