Doing a PML is not bad. Just read the write-ups for it and follow the instructions. The best advice for doing a PML is to spray the nuts with PB Blaster, Liquid Wrench, or some other penetrant. Spray it heavily, and well in advance (several days is preferable) to doing the work.

Be sure to take the weight off of the front wheels when you do the torsion bars. With respect to the torsion bar adjuster, remember that the top nut is one you need to loosen, the lower one should be welded to the frame. Just loosen the top nut so that the bolt is not locked by the two nuts, and turn the bold in. BTW, the nut should be 19mm so if you don't have a wrench that size you will need to get one.

When I did the shackles, the spring pack would not drop down enough to line up with shackle. To move it down (I was doing the job solo), I placed the factory scissor jack between the spring pack and the frame and opened the jack to drop the spring pack down.
