thanks for the links

unfortunately the rear is leaking now, otherwise I would take your advice and leave it.
I'm assuming the seepage is coming from there, but regardless I want to fix the leak so I might as well do the bolt at the same time.
As for the panhard bar, I'm actually just going to eliminate it all together because I have a triangulated 4 link, and technically I shouldn't even need one.
Years ago I was chasing a handling issue and I just put the bar on thinking it might help, but it didn't do squat. And now that I've sheared that bolt I sure as heck won't be mounting anything to that again.
