Marc, I just changed my rear knuckle bushings and it took me about 3 hrs from start to finish. Just a pain to remove EVERYTHING from thearm piece, You have to disassemble the whole rear suspension and arms and stuff. I did it with an impact and had no problems with any bolts.

All of them are either 14mm or 17mm.

When you have the whole piece in your hand and are taking out the old stockers ie:burning or chisel, Make sure you get the thin metal sleeve out too or the new bushings might not fit. You'd know what I was talking about if the stuff was in your hands.
