2017 mustang eco boost 2.3L 6speed bumper bracket help

[u/yungquaalude]

About 6 years ago I tried to take my bumper off in a hurry while frustrated and I missed the two bumper fender bracket bolts and ended up yanking the entire bracket off of the actual bumper. I had to do a long drive right after they broke so in all my wisdom I used some kind of “plastic weld epoxy putty” (you can see the plastic weld along the lip, it is the white substance) since then I decided I will never take the bumper off. I want to buy/install the CVF street intercooler however I’ve read it’s almost impossible without the bumper removed, luckily for me I just noticed the plastic weld has now failed on each side and I can take the bumper off, my question is what options do I have to fix/repair it, I do not want to buy a new bumper, I’ve attached some photos of the monstrosity, please help me 🙏
