Tank stand for 65g RR

[JCSReefing]

So I am purchasing a 65g tank and figure I would build the stand first. The tank dimensions are 36.4x18.4x25. I made the stand frame 37Lx18 1/2wx36h. I'm nervous I didn't leave enough on the width. It's sort of a standard sized 65g reef tank so figured I would ask if anyone thinks this will work or start over?

Does anyone think I need to put a center verticals brace on my stand for a 65g? Or is what I have sufficient? See update pic below.
