What is the lug pattern on a 1972 Chevy Impala?

The lug pattern on a 1972 Chevy Impala depends on the wheel size and option package. Most had a 5x4.75" bolt pattern (five lug nuts on a circle with a 4.75 inch diameter). However, some rare options might have had a different pattern. To be absolutely certain, you should check the wheels themselves or the owner's manual if available.
