Struts for the earlier years work fine on the 88's. (It's your only option!) Keep in mind though that the springs and the "hat" are unique to the 88's.
I should add that possibly depending on the brand of the struts, there is a very minor bit of grinding that sometimes needs to be done in order for enough camber to be dialed in. If you can't find one of the threads using the search function where this procedure is described, someone might post a link.
