Tom, you can do this one easy! Like Steve said, jack up the car so the tire is hanging free, when you loosen the bolts the whole strut will drop down so remove the cap nuts slowly and evenly or let the tire rest on the ground before unscrewing and then jack it up so the bolts clear the holes by about an inch. Reach up and remove the spacer. It's a good idea to brace the car, move the strut out of the way and clean and rust prevent the contact area. when re-lowering the car to re-bolt the strut it would be helpful to have a friend around to line up the bolts, it's easy but go slow. Also, while you have the strut separated from the body check the upper strut bearing for ease of movement or excessive wobble.
