Grade 8 all the way, bolts and nuts are relatively cheap, why not use the good stuff and avoid a few headaches, broken bones or dead bodies...

For a mock-up grade 5 is okay, but not for actual use.

No problem at all. You are gonna have 8 of those 9/16 bolts holding your axle on. Each one of those can probably hold several tons.

grade 5 will be fine. I have not had a problem in 5 years running 33's. Grade 5 will streatch a little when you run them, so you retighten them 250 miles later. after that they should be good. Grade 8 is good too if you can find them at a good price, just not necessary.
