vehicles spindle (i.e., hubs for a 1945 Buick spindle will not fit a 1971 Buick spindle).
•Verify wheel clearance utilizing Figure 2.
•Inspect the package contents against the parts list to ensure that all components
and hardware are included.
•Verify the new hub stud pattern in this kit matches the lug pattern of the vehicles wheels.
