Interchangeable seats between 90 and 110?

Hi
I am new into the defender world and would appreciate some guidance on the seat interchangeability between the 90 and the 110 series.

Are the 3rd row seats for the 110 the same as the rear seats in the 90 (2013 model)?

In other words, will the 3 rd row seats (with brackets/mounts etc) from a 110 fit in a 90, which does not any mounts/brackets available?

thanks for the help in advance
