Upper Control Arm Camber Bolts

I literally just got done with mine.
One of the single biggest pains in the rear ever.
I spent FOREVER using the Milwaukee "torch" blades in my sawzall.
I need torches.
Also as stated NO AMOUNT of PB blaster, Kroil oil or ATF and acetone "home brew" was helping.
I tried for a week

The "front" set cam apart no problem but I had to make a cut at either side of the bushing with the rear.
I was close to trying a hammer drill, but hammering manually was like peeing in the wind.
( I also didn't have a hammer drill )
