Hopefully this is the right thread to post this.. I recently was given a second hand tank with the measurements 72x16.. the tank is in pretty good condition but has NO brace and and frame needs to be replaced.. the problem with this is that all the frames im finding are only for 72x18 size tanks.. does anyone know where I can find a frame for a 72x16 or know of anyone who could make me one... thanks for your time.
