Are the new tops dependent on the center brace(s) for support, or do they 
just have gaps where the braces would normally be? If they don't need the 
braces for support, you could get a few strips of Acrylic or Polycarbonate 
sheet for a few dollars and use them to fill the caps in the Versa Top 
where the braces would normally be. Just a thought...

Chances are plate glass will be fine for your application. Almost all tanks 
are made of it, and the only use of tempered glass I am aware of in a 
mass-produced tank is the bottom of All Glass's 75 gallon tank -- and even 
there I think it is an option.
