Hi, I have an older American Titan SS filter Model # 584090. It is 48 sqft. area and 96 GPM. It is 22 inches in length and height and 52 inches wide. I would like to replace the interior grid assembly. Would the one I see mentioned for the filter above (59023400) fit my needs or would I have to buy a new filter (Pentair). Is there a replacement grid? Thanks
