5-Lug Wheel Bolt Pattern Measurement Diagram - A, B, C Dimensions Explained

This document is a small illustrative diagram (uploaded as "5lugboltpatterns.jpg") showing how to measure a 5-lug wheel bolt pattern. It depicts a dashed bolt circle with five lug holes evenly spaced around it. Three measurement lines are drawn and labeled with single letters: "B" (green) indicates the center-to-center distance between two adjacent lug holes; "A" (red) indicates a diagonal measurement across the pattern between non-adjacent lug holes; and "C" (blue) indicates another cross-pattern measurement from a lug hole toward the opposite side of the circle. The diagram contains no numeric dimensions, no year/make/model text, and no part numbers — it is purely a geometric reference showing which distances (A, B, C) one would measure to determine or verify a 5-lug bolt circle. A reader can learn the three characteristic measurements used to identify a five-lug bolt pattern, since a 5-lug circle cannot be measured directly hole-to-hole across its true diameter. The document was filed under a 1976 Ford Bronco, but nothing in the image itself confirms or contradicts that application; it is a generic measurement guide applicable to any 5-lug wheel or hub.
