Filter replacement or parts

I have a Hercules PH II-50 filter.  The lid has split.  I can’t seem to find a replacement 10" lid.  Will another manufacturer lid fit or do I have to buy a new filter?  If I need to buy new, what type of replacement would be good that does not require a great deal of new plumbing/pipe replacement. THANKS

Unfortunately, the lid for that model is obsolete and there is not a suitable replacement. A complete replacement option would be the Hayward W3C500. Click Here to View More Details on the Hayward W3C500
