Bit of both.....undo the 2 bolts back or front and you can get right in there....otherwise takes 2 mins to drop all 4....i tend to shove a rag in there which gets most of it... As in....to be a bit more exact...the 2 brackets stay bolted up (they take about 2 mins to fit) there are 4 more M6's and nuts vertical (those are the easy ones to remove...)
