hmmmmm, ok, I just can't find any place that sells a single large sheet of glass at the right size and the right thickness and right type, also, where'd you get your panel from? you said CL, but what is that
Your local autoglass companies should have it or be able to order it for you. You will want tempered for safety. You can also buy shorter panels and silicone them together front and back with other narrow panels and place a post at the seam on the outside.
CL = Craigslist
oh, I wasn't aware they'd do that just for you specifically, the problem then however is getting it to where you need it to be.
You will need either a machinery or, if it is liftable by hand, as many able bodied men as needed. You might need both.
