i just want to know if there are any difference between this cars i have this two cars and need parts from one to put on the other will i have any trouble?

 

naw the parts are interchagable

 

false, there are parts you cannot use from 88 onto a 91 and vice versa. trust me ive tried. Alot of stuff is interchangeable depending on what it is but i do know guage clusters dont fit unless you customize it, you cant use different windows in doors because 88-89 has b-pillar seat belts and 90-91 has the door seatbelts. They have different doors and door panels, 88-89 have smaller garnish behind the window with different trim, and 90-91 have a thicker garnish and round trim.
