If it has a glass brace, I am not sure if a stock trim piece will work unless you remove the plastic brace, or the glass brace is offset enough not to interfere with the plastic trim. Every tank that I have seen with a glass center brace does not have the top trim. Even so, my experience is obviously not universal, so there may be a way to make it work, or there may be a trim piece that is made for that type of tank.
Freedom is the sure possession of those alone who have the courage to defend it. -Pericles
Let every nation know, whether it wishes us well or ill, that we shall pay any price, bear any burden, meet any hardship, support any friend, oppose any foe to assure the survival and the success of Liberty -JFK
