Seat from 9000 inside 900

[misu]

Do You know if it is possible to put seats from 9000 into convertible 900? I mean if it is possible to mount backrest and seat from 9000 into chassis of 900 seats, what are tiltable. I do not want to mount 9000 seats as they are (I would need to modify front beam and rear mounting points, because I have an old style 900, with just anchors, not screws at rear), because I need them to tilt forward (because of children).
Second possibility is to change upholstery only (that is the reason, why I want to do it - leather of original seats is badly damaged), But I know, how hard this work is (I did it already a couple of years ago).

Here is what I know. I know that a 900 with passive restraint from 1988+ has the same bolt pattern. I know that later 900's like 1991 have the same bolt pattern too. I am stuck in a situation where I need to weld in some seats. I got some aeros and I have an 88 without passive restraint.
