I don't think that there would be enough room between the seats in our 1996 Plus 8 for a behind the gear stick (on the tunnel) tray(its hard enough to insert the seat belt tongue in the slot as is, to fat did I hear someone say).
As Johnplus8 suggests, there may be enough room in front of the gear lever between it and the radio. Let us know how it turns out John, it's a good idea.
Happy Miles.
