Here's what I have Deebo. Not sure if it's from a 500 or 250. I believe its a 500 cause its mure squared off if my memory serves me right. Since I was blessed with a pay it forward recently you get the same love if its what you need I have no screws for it and no gasket. Just what you see here.

On the one I have, the screws are stripped out beyond being able to remove.  I may be able to get them out, gonna try today while I'm off work.  I'll let you know
