Mac MC 2205 replace glass

I am the proud owner of a McIntosh  2205 power amp.
While moving I managed to crack the front glass
in a number of places. I have a new replacement;
what I do not have is the knowledge of the procedure.
  Does anyone have a written procedural manual for the
glass replacement on a Mac 2205 power amp? A photo spread 
complete with photos of each step would be great!
