Yup I had to do the same back then when I was like WTF are the bolts $25 each, now they are prolly $40+. I still have the old ones as they were in good shape, perhaps I should use for a future project.

The main problems with any bolts along the manifold and exhaust is the heat they experience, thats why a lot of times they use copper or copper coated nuts because with the heat and exposure to the elements they wont rust like steel and disintegrate or seize up.
