are these superstock wheels?

i got these wheels recently..
2 are 6 1/2" wide and 2 are 7 1/2" wide
they are either from a 64 dodge or an 66 imperial or chrysler something.?
they look identical eccept for the width difference.
they also look like a matching set as far as i can tell..(4)
what car would have come with  different width wheels?
ill be making sure a b body rotor bolt pattern fits them as they dont
look like the large imperial wheels.
cheap
