Is it possible to find the same nut that is use to bolt the exhaust manifold to the head at Home Depot or places of the such. I know I can just go to a junk yard, but I would like to know if I can get it somewhere else. I destroyed mines

Thanks for your help...

 

they arente really expensive from the factory and at least you know youll be getting the right part. Im sure you could find a nut from a hardware store that will fit its just a matter of if you want to do it right.
