What exhaust hardeware do I need?

[dan2286]

I need to get the down pipe attached to the manifold, but I don't know what hardware I need to use. I am not sure if I need the bolts with springs or just studs and nuts.

I have a stock #5 exhaust manifold for a late 70's Olds 350 that came with a cat. It has a 3 bolt flange.

Thanks for the help.
