help on headers

So I was installing my new O/R h-pipe today, and one of the bolts holding it onto the header sheared off when I was trying to take off the old midpipe. So right now, the new h-pipe is being held on with one bolt on the driver's side. My question is this, how can that stud be fixed, how much will it cost to get fixed, or do I just buy new headers? I've considered new headers, because I will be buying a KB in under a month, but the KB will be soaking up most of my available funds. Suggestions?

Let me clarify a little.... I'm not for sure going to replace the headers. I'm either going to fix the stud, or replace them. I'm just wondering how much cheaper it will be to pay someone to fix the stud, compared to me buying new headers and installing them myself.
