Those pictures don't really show a lot of detail.
But I can see that the first picture doesn't have the torque box, and does have EGR. So it's probably a 96 or so with an automatic.
No later than 97, because I see it has a front canister. 98 did away with it.
And the second picture does have the torque box and doesn't have EGR, so it's probably a 98 or something with a manual. Doesn't have front canister. But someone has been messing with it, in that case. Because it doesn't have the cover thing over the crank gear for the timing belt. All manuals have that.
