I have a St. Croix Prescott EXL manufactured in 2005. It does not have the 3rd clean out behind the ash pan like the ones made in 2007 and later and as shown in the graphic below. Would someone mind measuring the dimensions of the opening, location, and cover size for me? I'd really like to install one in my stove. It is a real pain to get to that ash trap with out the opening and plate there. Also is there a gasket or sealant used on the cover? I would really appreciate the help!
