this is the guide i used. Only thing i did different was rattle gun the top retaining nut off. And if you take off the bracket holding the brake lines to the chassis you can pull the top of the strut out to miss the guard and leave the bottom bolted in.
iv only done it 2times now and got a spring swap down to 20min a side.
