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:

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. _________________ 84 Camaro Z28 - LS1/T56
