roll back odometer?

I experimented on a dash which was junk, thought it would be nice to see if possible to start at 00000. . i messed it totally up and plastic stuff broke.
It must take some careful finesse to get those units apart.

"If some one asked if it was OK to wipe their *** sideways , There would be somewhere that it would be illegal."

Pretty sure that (sideways thing) is illegal in most of CA.
