I've always had trouble with my baffles warping in my Regency F3100 ever since the originals deteriorated,all my replacements Warped big time,I bit the bullet and purchased a slightly over sized piece from Lynn manufacturing cut 2 pieces out making them fit even tighter than the stock OEM ones, much to my surprise they are holding up way better than I thought they would,half the price also,as this is discontinued the baffles may be harder to aquire and Lynn hasn't disappointed,any one ever need some I wouldn't hesitate to purchase them,hope this helps someone in need,stay warm
