I have a Lopi X-NT (Revere) that was manufactured in 1994. I rebuilt it 8 years ago. The two baffle supports are sagging and need to be replaced. Removing the baffle support I noticed the ledge on which the bypass support rests is bowed as well. There is a little sagging on the top cook surface. I could replace the rock wool gasket for the baffle support but maybe I should just replace the whole insert. The stove has been overfired a few times. Please take a look at the picture and let me know your thoughts.
