For the rear struts you could go with monroe. They should have a quik-strut setup where all you do it just remove the old, slap in the new and call it good. If they don't come with upper strut mounts then you will need those too.

If those are too much $$$ then you can get just the strut and new upper mount and install yourself, as long as you have a way to compress the spring safely to remove it from the old assembly.
