M7774R Caps

need pool caps. We have a 2002, 21’ round pool by Mignon by Aqua Leader, has number M7774R stamped underneath

You have a Trevi brand pool. Unfortunately, we do not carry parts for Trevi. We recommend trying https://www.trevi.com/default.aspx

Has anyone found where these can be obtained?  I’ve tried to contact the company but receive no response.  Is there another part that will work?
