Exhaust Pipes / Bolts 1957 Chevy.. ???

Im Looking for a Place to buy the bolts and little cups for my Ex / Intake Manifold.. 1957 Chevy 235 inline 6.... Also can anyone please tell me where to find a detailed diagram.. For the Exhaust system.. I need to know what type of gaskets are needed and how it was assembled Org...Seems there should be a Ring/Donut gasket in there...??? I tore a hole in the pipe.I bottomed out on a high curb .. ... Im gonna have a new one bent.. Coming from the EX. Manifold.. To the Cherry bomb..
