If and when I next take the seats out I think I'll cut the metal off behind the seats and put some oem style rubber U trim on the fibreglass to tidy up the edges.
That is what i did.
Keep in mind that if it ever comes to resale it may not be to everybody´s liking. (ie butchered, unsafe etc)
I love my rear visibility now.
