Nissan Largo Friends

Hi everyone, Im looking at buying a nissan largo but want a petrol with 8 seats (due to a fast growing family ive found one i like but its only 7 seats. Does anyone know if i can simply remove the middle row of seats and buy a new 3 seater row and instal that?? and if so where is the best place to get a new seat ??
also what info can you guys give regarding a lpg conversion??

8 seater is different set up from 7 . The 8 seater is on rails and would require the whole interior really. Best bet is to buy fresh import 98 . Think ringwooddan was selling one.
