Broke my AC panel control arm

[PbFut]

I have attached two photos of my AC panel with a broken upper lever. It appears that the factory secures several points by hammering them over, rather than using nuts. There are many options available for replacement levers to address these commonly broken parts. The new levers includes a point designed to be hammered over, which may be achievable, but I am concerned about how tightly this joint can be secured to match the factory feel.
Additionally, there is a cap over the shaft that holds all three levers in place. What is the recommended procedure for repair? Should I grind off the rolled-over head and then use epoxy to reassemble the cap after replacing the broken arm? I am inclined to simply epoxy repair the broken arm without disturbing the multiple factory rolled-over attachment points.

Has anyone succeeded in repairing a broken arm to a factory feel?
