only difference is the t-case and shortened rear d-shaft. try car-part.com for a t-case. you'll need a 23 spline input t-case, so any 4.0 case after late 89 will work. if you get limited years returned in your search, then bump it up to a later year. you could also go with a 23 spline 242 t-case and have awd available to you later on. :D
don't forget to get the bellhousing with the trans. It may sound like common sense, but I've seen transmissions sold without it and just want to make sure your project goes as smooth as possible. :thumbsup:
