Greg,
Thanks for the resorce on the rivets, I have one of their catalogs on my desk. I'll take a look tomorrow. I need to replace some rivets on my frame. I was going to use bolts, but like the idea of using rivets. It will take me back to my blacksmithing days.
Wally,
The Ace Hardware owner is a friend of mine; when I asked him about the nuts he said he can't please every customer. That was after I told him that stocking the grade 5 nuts would solve both needs. It's a small store, but he does have a good selection of grade 8 nuts and bolts.
