I'm not sure of the years that will fit but the 88 won't for sure, The 95 had electronic controlled shifting and sensing. Hopefully some one will post what they know about what will fit. Searching here,
Car-Part.com--Used Auto Parts Market, it looks like 91-95 will work. That would have to be your choice. If you're plannng on keeping it, why not have it rebuilt and you'll be done with it. A used one may fall apart in a short time.
