x2... reuse if you want (I would)... buy aftermarket bolts... or bend over and buy new OE if you want.

We've seen plenty of posts of people reusing with no issues and a few where a rattle was detected. I'll be reusing mine, and in the event of a rattle, replace them with aftermarket. Buying $16 bolts sounds way too much like buying $100 HDMI cables to me.
