I removed my fenders on my 73'. Breaking a bolt(there were 2 bolts) underneath on the fender right in front of the door. I believe that is the Firewall... How do i go about retrieving the wrest of the bolt? also, I tried to put the fenders back on after i removed the inner skirts and they didn't line up. Could this be because of the bolt I broke(one on both sides, but the same spot)? -Thanks in advance.
