You can go on line to places like Dr Foster Smith or one of the similar ones and buy 6 ft pieces of hinge for the glass and 6 ft pieces of the plastic back strip for a glass lid. Then all you need to do is go to a local glass shop and have them cut a piece to fit the space you want. If your t5ank is a standard size where you live, you might even find a glass top at the LFS. I got my last piece of back strip[ from my LFS because they happened to have some that they could sell in bulk.
