Just did it on a set of 1968 Dart fenders. The first thing you have to do is cut the nose of steel fenders about 1/2 back removing the flange. Then cut the outer skin of the fender saving the area you want to mold on the fiberglass fender. Position it on the glass fender using the headlight bezel for proper location. Go to NAPA and get the epoxy adhesive called Plastic Welder, great stuff but you have to work fast once mixed. Glue the steel bucket to the glass fender in proper location. Once hardened I finished it off by mixing fiberglass resin and cut up cloth and blend in surfaces together. If you need pictures post your home email and I will send pics of mine. Take you time and good luck.
