Sure - take the old one out and put the new one in where it was.

Seriously - why do you ask?  What are the problems you're having?  You'll
have to remove the glass - should be bolted or clamped to the regulator.  It
will probably just come up through the window slot then and gently pry it
free of the window opening.  The regulator may be riveted together,
requiring you to grind off the rivets to get it out.  I've never taken one
of these apart, but I can't believe it's much different than most other
cars.
