FSM for a 91..will work fort 89?

[TheTimanator]

I have an 89 fastback, with no motor.  Are most of things the same between an 89 and 91? (besides the engine)  The guy is gonna sell it to me for $59 shipped.  Its used though

I would bet that it's very similar minus the engine parts.  I'd pick it up...also, you might want to do some searching on the online forums, (this site and FA), cause I believe somewhere out there is a complete FSM online in PDF version.
