More welding ...
This is one of the flanges at the lower, driver side corner of the radiator window. Displaced by bending the upper section forward.
Flange removed with a hack saw.
Make a pattern out of heavy paper and cut out the patch piece. Not sure what the notch is for in the original, but figured I better include it.
Test fitting the patch after doing the final trimming. Don't sand off the E-coat ... heat it slightly with a propane torch ... it comes off very easily with a wire brush while still hot, leaves clean bare metal.
