Thanks Guys.
I really don't want to pull them out again if they don't fit correctly. (idea just came to mind)
So C is locked in for the outers.
And I'll go with the A option, as my wagon had been redone, and the outers were in upside down, So I'm not going to trust it as a guide for the inners.
Blacky thanks for checking the others, it sounds like they might be original.
I also noticed that the inners do seem to have a flat edge on one side, so it's probably the part to glue unto the back.
I'll have a look at the Rare Spares instruction video again, but it doesn't really mention of show the profile.
Idea

- I'll just do the rubbers on one door and put the door back on to ensure everything is OK before doing the rest.
Last questions ?

I was going to use "grease and wax remover" on all the rubbers and gaps before gluing. (Is that enough)
And, do I need to use anything on them after installing, to help bed them in.
I'm sure I saw something mentioned about this ?
