It is undetermined if any covers will appear on the track-listing.

The 6-fold cover of M appears in the centralizer 2.3.

This cover also appears in the film's end credits and soundtrack.

The motor mount cover with its four recessed bolts appeared just before him.

A cover of "Part I" also appeared on the soundtrack album.

The covers have appeared on the market from time to time since then.
