While I'm waiting for parts I decided to pull the sway bar and dismantle the side with the broken spring (waiting to borrow/get a pair of compressors for the good side).
Taking the sway bar off was super easy like most cars. I disconnected the front underbody panel at the bumper and the swapbar slid right out.
The "hat" that slides over the strut took a little effort to work free, but it came off with some light tapping.
I don't see the "hat" listed on any of the parts diagrams and it did not come with the new struts. Mine look like they'll be serviceable with most of the rust having come from other parts as the "hat" apprears to be galvanized.
