steering box woes

I planned on replacing it...... I tried to get it loose first. No such luck with that...... It's stuck in both ends! Not sure of the brand but it's pretty beefy. The screw head deformed, and the ears bent on the body of the puller..... I hit it hard with my biggest hammer and nothing. it's like its all one piece of steel...... The pitman arm on the manual box popped right off so I'm not sure what options are left
