I have a 10 year old Castile Insert model I and have changed the door gasket 2 times in the past. This time the tabs that hold the glass in position have snapped off. Only have 1 tab holding the glass in position. My question is: Does the newer door frame with the rods holding the glass in position fit my older model stove and does the glass panel from the old door fit the new door or do I have to replace that also? Thanks for any help.
