drum brake gurus needed

[seattle gmc]

I pulled the rear drums off my truck so i could splash some paint on the axles hubs this weekend, and notice that the bar under the wheel cylinder is rubbing on the hub and wearing through the bar. I have attached two pics of both sides for comparison. The bar on the passenger side has clearance and is tucked nicely up under the wheel cylinder and looks straight and flat while the other side is bowed out and down. What might have caused it to bend out like that? Should i just take that piece out and pound it flat or should i go about replacing it??
