Grab your trusty AC recharge kit, place the end of the recharge hose against the ends of the bolt and open the valve. Frost it up really good. Then using a drift, smack the end of the bolt. The freezing will shrink the bolt and help it turn loose. Dry ice works, too but takes longer. Putting heat on it will swell the bolt. You can alternate heat and cold
Hope you're taking it loose with the 3 bolts at the top and not the center strut rod nut. Removing the strut rod nut can cause it to fly apart. Best to get it out and then compress the spring.
It's strongly suggested to get 2 NAPA 264-3664 camber adjuster bolts. Makes alignment much easier.
