Really it's going to take you TOPS 1 hour per side. I say tops because your going to have to jack up the car, take the tire off and of course re-install the wheel/tire. There are two bolts that hold the strut on on the bottom and of course the one nut under the hood.
Just remember that your probably going to have to have her alignment checked. No worries it's not going to be out enough to prevent you from driving her safely to an alignment shop!
To be honest when removing the old ones I don't have a preference as to top or bottom mount points that I start at but when re-installing them I always install the top first, leaving a little loose, then pick the spindle assy. up by hand, install the bottom bolt loosely then just swing it up till the top hole aligns.
I know it probably sounds confusing but I'm telling you, once you do one side the other will take half the time and you'll be kicking yourself for sweating it... if you get into any trouble you have my number!!!
