The bolt is an M7 metric, Ron Ayers sells it for $2.35 and probably $10.00 shipping. You can buy a stainless bolt that will look good at Ace Hardware, buy 4 and make them all look the same and no one will know. You can probably get all 4 at Ace for lesss than $5.00. You can chase the hole with a Tap, should be pretty easy to do.
