Most vendors will have bolt kits. Mar-K, Classic, Jim Carter, etc..
Since I am going to paint the bolts (carriage heads) I went with the standard. Would have liked to go polished stainless, but $$$$$
Let me/us know if you need any help along the way. I just finished the wood for mine. Still working on paint, etc...
Here's my picture album. Hope this helps.
