A gal ran a WANT listing in Craigs List last week for a front sway bar for a 123 chassis. I called to tell her good luck, no one saves them when a car is scrapped out theres too much work involved. I asked her how it failed, she said it happened when she hit a pot hole in the road.
BTW San Jose, CA is the worst area in No Calif for pot holes! the roads there are really bad.
Good luck w/ the damage from the road construction site, I would go there when some State employees are on site, get the foreman's name and tel# and go from there. take a picture of the hole (or whatever was the cause of the damage)! I carry an old camera in the trunk of my car for this type of thing, or an accident whichever occurs, fortunately I have not had to use it yet.
