Here are the rough years I'd look for, to the best of my knowledge.
This is by no means accurate so hopefully others will chime in with more knowledge on which years cross over!
-As far as I'm aware, the roof rack looks basically the same through all years in the '80s, to '91. You might find the woodgrain varies though.
-The rear quarter panel I should think will be the same all years, although if you want the bit around the taillight too that will be '84+.
-The doors have some small detail changes over the years, so I think you'd be best looking for a similar year for those, probably anything ~'80s.
-I'm not sure on the hood pegs, but they'll probably be the same through the '70s and '80s, to '91.
-The grill should be a "pig nose" which ran from '79-'85.
-The clock will be different from '86+, so you'll need something earlier than that.
