If the droplinks are the ball-jointed type, then the threaded lengths will probably require a Torx bit to hold them still whilst you undo the nut. If this is the case, make sure you apply plenty of WD-40 (or similar) a good few days, every day, before you attempt the job. At worst make sure you have as much elbow room as possible, and plenty of patience.
And make sure you have the right size bit too. With Torx bits you might find the bolt a little bit bunged up with grime and decide the next bit size down is a good idea - this is fatal - as you'll find the smaller bit just slips and rounds everything out. Unless it splits the Torx "hole" in the bolt head first - then you really ARE knackered!!!
I'm not trying to dampen your enthusiasm Doofah - just make sure you are well prepared and take your time. I've found that Torx fittings only spoil once -you can't easily file new flats on these bu**ers like you can with a nice hex-headed nut or bolt.
If you have the older style with just two normal sensible proper bolts holding each link on then it's a real doddle. These ones are actually a pleasure to do because of the massive improvement for such little effort
