Pontiac Repair: Broken Bolt, napa auto parts, auto parts stores

Question
Hiya!  While removing the starter for my 2002 Pontiac Sunfire 4 door, the bolt that holds the starter in place was broken.  (M10x1.5x78mm)  I have contacted the dealership along with every auto parts store (and even the regular hardware stores) in my county.  No one has this bolt and Pontiac claims that they are no longer manufactured.  Where can a girl go to get a silly bolt that is making her life completely immobile?

Answer
Hi Sarah:

where do you live? If you have the bolt size then you should be able to find what you need. NAPA auto parts stores have all kinds of hardware you can get it there. Carquest auoptparts same thing.. Even some of the big box auto parts stores like autozone/advance auto they have pre packages bolts for just what your looking for.  There is an isle in those parts stores that has all that kind of stuff like bolts nuts handles and switches. I have seen them packaged by a company called "help"
