Stock ones work fine! I wouldnt even change them out. Just use them till you need another set if you even ever do. The stock bolts have held up on all the trucks if seen them on.

Got my bolts at Ace Hardware. Grade 8 I think. Only a few bucks to replace them all. After breaking one off in the head during an engine swap I figured new bolts all around is a cheap way to avoid tapping and drilling again.
