To me that looks like aluminum fins on copper tubes, I have repaired lots of them it is not hard,I pull off the aluminum fins around the hole, clean the copper tubes really good , heat up the copper tube and put a drop of silfos on it I use 15% silfos, if it is a steel frame on the end I burn it away with a oxy acetylene torch eather with a cutting tip or just increase the oxygen and oxidize it away, when I tried to pry it away I end up making other holes so I started to burn it away
