Fitment & Compatibility

The table below also lists later applications through 1989; confirm that their spindle and bearing arrangement match the drawing before ordering. The supplied aluminum hubs carry 1/2-20 studs. This front brake kit does not include a master cylinder or require a parking-brake cable; those unrelated rear-system notes do not define the front installation.
