I don't post much anymore but... I had to login just to say that those are some of the best rust repairs, replacements I have ever seen. I'm really impressed by your work.
Very Nice! I just started my cowl repair, and when I saw this thread I thought, boy I'm glad I don't have to repair the door jambs. After getting the cowl apart it looks like the left jamb needs a little work. I hope mine turns out half as well as yours!
