I wouldn't personally undo it from the top first. You'll never get the strut out. You need to get a windy gun of some sort and some spring compressors. That's from experience. I stripped down the legs twice and couldn't undo the flipping thing.
Looking at that pick are you on jacking up one side to remove the leg. You need to get the whole front end up mate. It will make life alot easier. Releasing and re-fitting the strut is much easier when there is no pressure through the ARB.
