It's an 88 almost positive maybe early 89 if its an 89 it more then likely be 25 Anv. And there would be a pon on dash Some are not but it looks like mine and 90 they did the other steering wheel I say 88
87-early 89. It has the 85mph speedometer so it cant be late 89. Also 87-88s, except California 88s, were speed density instead of mass air flow. But there is a good chance that even if it is an 87-88 it already been converted to mass air by a previous owner.
