what is the difference in LX450 seats and fj80 seats? In my search for new junk yard seats i might have found some LX450 seats that will work for me. But how are these different from FZJ80 seats? Is the cushion and leather and everything different? Are new cushions available from Toyota for them if i needed to rebuild them? Are they generally softer or firmer? Do they bolt right up? Are they close enough that my tough duck covers will fit on them?
