just finished fitting the rear tie bar bushes but while i was under the car i ad a look at the wishbone ones!!

they look pretty difficult, what do i do with all the load bias valves, does all that av to come off? does ne1 know ne shortcuts? also the rear a/roll bar bushes dont seem to be bolted to the rear chasssis theyre just sat on the bar acting as more of a bump stop, another problem is the threads are covered in under seal so laying under the car trying to undo them is going to be a nightmare!! ne help much appreciated
