I don't know Denny. I think I will try some bar clamps,some pieces of 2x4 too spred the load, a little WD-40,and a some heat. I snuck into moma's kitchen put the wind wings in a lasagna pan of water on the stove. When the water came to a boil I used a pair of welding gloves and the old glass slid out like butter. Wish I had used heat for the side glass that was a battle!
