installing third row seats in 1992 montero
 

Good evening I am looking at purchasing a 1992 Montero but was curious if it was to difficult or even possible to install the third row of seats? I have found one with low miles for a good price but it has never had the third row and due to my family size i would need it. Also If I could get some feedback on the positives and negatives of this year it would be greatly appreciated. It is the base model with the manual transmission.

Thanks in advance,
Jake
