Don't worry about the fender extensions, but have you had a chance to get to the bumper as I have someone that may be able to pick it up for me over there but time is of the essence.
I have only one fender that I'd be willing to cut up (passenger side), but it also looks like that the extensions that you had photos off are a bit different anyways. You might be better off finding whole fenders.
Here are some photos of the bumper. The chrome is mostly shot, but it's straight and could be re-chromed I think. There are two marks from a bumper jack on the bottom, but I. think that would be an easy fix. I had this bumper on my car for years. $100? I'm in Eagle Rock, CA 90041
