As I understand it, mean structures just mean that you constrain one
of the loadings of your measurement model to 1, which means that the
unit of that item also becomes the unit of the latent variable (rather
than equating the unit of the latent variable to a standard
deviation). In that case the answer is yes, just impose the
appropriate constraints on the loadings.

Please read the Statalist FAQ till you understand why this is not
acceptable on this list and repost a corrected version of this
