To answer your question simply, I would say YES, that could likely solve the problem.
I did consider trimming it, but opted against it for fear of altering its appearance too much. The actual hinge hooks were binding between the radiator and the brace, so that’s why I trimmed them off. I tried to re-fabricate the hooks with wire, but it didn’t help. I did also trim the bottom lip edge off the radiator itself hoping it would allow things to settle down toward the brace more, but that also didn’t help.
