if you look on outer end of torsion bar [just in front of wheel through hole in sill] you will find that it is threaded so that torsion bar can be pulled out,this of course if torsion bar is not seized ,which they will be!.....but if not jack up body so that there is no weight on axle,wheels will be just touching floor,-may need one end of shocker disconnecting,[mark both ends of bar for reference]-then using slide hammer remove torsion bar,jack up bodyso that next spline can be used and refit bar ,repeat for other side[you may need to do this a few times to get correct ride height,[ make sure that inner bar reference marks are aligned each time bar is refitted and only outer marks are moving round] good luck...you will need it!
