There are some variations on some model years of production that require physical inspection of your Volvo.
1993 and some early 1994 850 models had replaceable ball joints. These control arm bushings will not fit the models with replaceable ball joints. You can buy the ball joint and bushings separately for those models.
These bushings will fit all 1995 to 1997 850 models that have the ball joint integrated with the control arm.
Some 1998-2000 S70 & V70 models had "4 bolt" style control arms. This bushing is for "2 bolt" style arms. These are not interchangeable. Please inspect your vehicle to determine which style is equipped to ensure you order the correct parts.
