I have a good looking plenum i could part with, how can I tell what year range it is from?

Assuming we're talking about the upper plenum here: there are several ways, but the quickest is to look for the triangular hole in between and below the front throttle ports. The later cars did not have one.

*Edit: These pictures are poor, but you get the idea:

its the later kind. I think i pulled it of an 89. interested?

Also, the '89 is considered later style due to the throttle body changes starting in '89 but won't have the MAP sensor port which 90-92 do.
