You definitely want at least grade 8 hardware. They should be yellow brass in color, with I think 5 tick marks on the head. Try and find a specialty hardware store in your area that sells the full fastener specturm. At home in Dallas there's a huge hardware store that has an entire aisle dedicated to just hi strength hardware. At a place like that, you could easily get everything you need for under $70. As for an itemized list of everything you need, you might pick up a factory assembly manual, or call our site sponsor or another one of the vendors to see whats included in one of their kits.
