Light frame lean on tank

[An ngo]

I just mount my 80/20 light frame into my tank. My tank is 36x24x24. Stand height is 32.25 in, light frame height is 86”. The issue I facing right now is my light frame stand right next to the back of my tank. There is only little bit gap bettween them, maybe 1/16”. If i hang my aquatic life light fixture. The whole light frame will lean foward and stand on my tank that may crack my tank. Any idea help me out, should I move it out or put some foam inside that gap to push light frame lean backward??

I'd put a washer between the vertical rails and the attachment at the top of the stand. Even just a 1/8th on an inch should be more than enough. If not, move down and do one washer at the middle brace and a couple at the upper brace.
