I'm in the process of restoring my first straight and on this one I'm not going to try and pin it but I'd rather like to get a bolt to hold it together. I looked at microfasteners.com but I don't know the sizes. Can someone direct me to the correct size bolt, nut, and washer I need to hold everything together? I know it should be 1/16" but I can't seem to find that anywhere.

Thanks.
