Well, my brother found one that was on a low hour fire unit i guess that is in real good shape. Ours is coming apart where the tube welds to the face plate at the joint. Must have bumped something before we got i guess. However, it sounds like i should put this insert in if i don't want future problems. Would you send me an email please - thanks for the help and reply! bclark@oneok.com or becfarms@aol.com
