Dustin, the shadetree way for a 5-bolt pattern is from the center of a bolt to
the outside edge of
another bolt, skipping one bolt between the two. Does that make sense? Chevy
4-3/4" diameter
pattern will measure "approximately" this way. It's not exact, but close
enough. I could give you
the trig formula to figure it exact, center to center on holes, but it's not
worth the pain to try
and remember it!
