I've got a 1971 14x48 Ouachita that I am rebuilding. The transom was shot, just crumbled in my hands. I have built a wood replacement but can't install without removing the knees. They were bolt to the transom, but riveted to the floor. After reading some older post I understand I can use stainless steels bolts if isolated from the aluminum. However I would like to rivet them back in place, as I suspect that would be a better option. My problem is I am unfamiliar with the rivets I would need or how to install, or the tools need to install. I've attached a picture of the braces.
