I have an old Majestic metal corner fireplace (Model M28) that's probably from the 1980's, and I'd like to put an LED insert into the opening but don't have enough room, so looking for any advice/tips. The doors came off very easily but I need to reduce the metal flanges on both top/bottom and sides, so before I start cutting metal I thought I'd check here to see if anyone has ever removed one of these? I've posted a few pics, but let me know if other pics would be helpful. Thank you.
