How to install 3rd row of seats ?

Hello.
 
My friend has Outie'07 euroversion, 5 seats and wants to install 3rd row of seats.
Our dealer can't say anything about it.
Is it difficult? Has anyone info about this installation ?
Is it really ?
 
Thanks a lot.

I wouldn't do it my friend, its not the seat it self thats difficult, but installing seat belts and removing trim ect. ect. cost of all the parts and the labor will not outweigh the benefit of the third row, unless you REALLY need it.

I dont think that you can without major modification. They come from the factory with or without the 3rd row seat. It is not an accessory "add-on".

I agree, you may be able to order all the parts to do a conversion, but it will probably be prohibitive.  the price difference between the LS 5 seats and LS 7 seats is about $600, but buying all the pieces to do it would probably be 3-4 times more.
