Hi again Janet,
Jumping back in here because I have found out about the issue you have having (sorry for taking so long). There was an engine design change in that year model. Prior to and through 2/89 was one engine, and it changed for 3/89 and after. Both 3.0L, but designed differently. From what I've been told, one is a side mount, and the other is a front mount - and which design is which for what production time I'm still researching.
Check your underhood sticker and the door sticker to find the production time and this will help narrow down which one is needed. The only other way is to remove the starter and match it with the pictures of auto parts stores on line -- or take it in to them.
Mid-model changes always cause confusion!
Here for ya. Glenn
