Nothing has been welded up what you may be seeing is the propane torch burn marks as I used it to remove the solder joint. So I will start with the hinge rebuilt and go from there . If I move the cowl forward it won’t help because the door won’t move any further forward and not because it is hitting anything
It is a good thing you didn't weld up everything yet. You will be able to move the hinge pillar forward 1/8" or whatever you need. I had to do this on the first basket case truck I worked on.
