Depends on the year Bonneville. Measure diagaonal across the wheel studs. Do not measure to adjacent studs. Go from stud to stud by skipping one stud in the middle of the 2 studs you are measuring

center of stud to center of stud 4 1/2 inches you have a 5 on 4 3/4 inch bolt pattern. Standard GM car pattern.

center of stud to center of stud 4 3/4 inches you have a 5 on 5 inch bolt pattern. Standard GM full size car pattern for big B body cars like full size Pontiacs, Caddys and Chevys.
