Keith I would hazard a guess and say that there is probably tons of other work that you can complete while waiting for your brother to come over and weld in new metal so don't let that stop you from doing the other things that need to be done.
Unforeseen issues aren't the end of the world in fact they are par for the course when working on a 46 year old truck, you should expect them and you shouldn't let it bother you, simply fix it and move on to the next issue like you have been doing for years during the restoration.
You have done an amazing job and now you are a few steps from the finish line, finish strong brother!
