Removing tie rod end ball joints

[Dave_Vrba@mail.sel.sony.com (Dave Vrba)]

     Are there any secrets to loosening and then removing (for replacement) 
     the tie rod ball joints on a '62 MKII Sprite????  Reverse threads or 
     anything like that???  Special wrench / tools to grip these wobbly 
     parts???  I've used penetrating oil but no heat yet.  Should I??
     
     I will have to get the alignment done I know, should I just have the 
     alignment garage replace them for me?
     
     TIA for help.
