Ladies and Gentlemen:
      In my capacity as special counsel for Cal Alta Auto Glass,
Inc., a Nevada corporation (the  Company), I have participated
in the corporate proceedings relative to the authorization by the
Company of a maximum of 10,000,000 shares of common stock
pursuant to the Plan as set out and described in the Companys
Registration Statement on Form S-8 under the Securities Act of
1933 (the Registration Statement).  I have also participated in
the preparation and filing of the Registration Statement.

	Based upon the foregoing and upon my examination of
originals (or copies certified to my satisfaction) of such
corporate records of the Company and other documents as I have deemed
necessary as a basis for the opinions hereinafter expressed, and
assuming the accuracy and completeness of all information supplied
me by the Company, having regard for the legal considerations which
I deem relevant, I am of the opinion that:

	(1)  The Company is a corporation duly organized and
validly existing under the laws of the State of Nevada;

	(2)  The Company has taken all requisite corporate action
and all action required by the laws of the State of Nevada with
respect to the authorization, issuance and sale of the shares of
common and preferred stock to be issued pursuant to the
Registration Statement;

	(3)  The 2,745,000 shares of common stock, when issued pursuant
to the Registration Statement, will be validly issued,
fully paid and non-assessable.

	This Opinion is restricted to the application of the Securities Act
of 1933.  I have not been asked to give or provide any review of the
application of the laws of any other jurisdiction.

	I hereby consent to the use of this opinion as an exhibit to
the Registration Statement and to the references to myself in
the Registration Statement.
Yours very truly,

/s/ William M. Aul
