QUESTION FOR UCA BALL JOINT SEPARATION

Ok, thanks cause I haven't done an upper ball joint, just tie rod ends. I have a torch and an air chisel and my compressor will probably barely keep up, really don't want to resort to either just yet. I don't have to save the ball joint, but will if possible. I'm thinking I'll try soaking with PB blast and seeing if I can bolt the LCA in with NO washers on either side of either bushing. I honestly don't even know if I can cram it in there with no washers but I'll try. I really appreciate the response.
