Some bad news though. With everything apart, I thought it'd be a good idea to brush everything off and hit it with some leftover rubber sealant spray I had left over from my interior re-do. I ended up doing this with just a wire brush.
Picture yourself as the right, rear shock, looking out at the sidewalk. This one makes me feel bad. I don't think it's structural or anything's compromised cause if I knocked everything out with a brush, it's been on its last legs for who knows how long. Nothing I can do right now, applied as much sealant as I could. At least I'm getting to know where are the areas of concern are when I'm at Phase 4 and take her in for bodywork & paint. I'm going to bite the bullet on this one, pay the bodyshop to fix it right, and move on with life.
