It looks like FJ80 was 91-92 only. 93-97 are FZJ80. As near as I can tell, there isn't much, if any difference - they just changed the name to make me look stupid. I'll never let that happen again.
Harris - I have my Vulcan hat on now - yer hammered.
By my calculations, the difference between a '92 FJ80 and a '93 FZJ80 is about .1%! So why bother researching?
