Can anyone tell me if the bolt pattern on a 66 Impala is 5x5 or 5x4.75?

Its Probably 5.4.... Etc 5.5 Was Early 80's I Think

it's a 4 ¾" bolt circle diameter, if measured from stud across to stud it's about 4½", I usually measure the radius, from center of stud to center of wheel and multiply by 2.
