What would I have to do

Ive got a tpis Cnc'd plenum from an 89 sitting around and would like to use it and Ive noticed that there are some differences from the plenum off my 87, what would I have to do use this on my l98, I think its the Iac passages that are different mine has the triangle between the throttle holes and the 89 doesnt I think it could be the other way around ill have to look, if i were to get a iac housing for an 89 would it work, Or would it work if i were to just put it on
