Internet scuttle butt says that years 1986-1989 are the same but I'm still not clear as to if there is a difference between the gimbals of a 4 cyl a 6 cyl and an 8 cyl drive . Seems like it would have been cheapest to just use one model for all power trains but you would not need something as heavy for a 4 cyl power plant as you would for a v8. I dunno , guess I'll go by the Y pipe design to match one up if I have to break down and buy another one. I know where 4 are now but the easiest to get to is for a 4 cyl. .
