Changing 8.75 axle HELP

I am running the OE 1 3/4 drum brakes. I purchased this rear end for $75.00 from a mother who was upset her son had left car parts all over the place when he moved out. I have had it completly rebuilt. When the OE axles were out, I had them redrilled for BBP. I had the brake drums drilled also. The drums still have plenty of life. I have a line lock in the car. I am not sure how the flange got bent. I probably would have never noticed it had I not had the car jacked up putting a new drive shaft safety loop on. I spun the wheel and noticed a drag. Started the car up put it in gear (Car is up on jacks, with front wheels blocked) and noticed a wooble.
