I checked all of my local hardware stores. I think Lowes usually has these, but they said their small parts vendor hasn’t come to restock anything in a long time and they weren’t sure when they would be coming back. All other hardware stores in my area didn’t have them or staff wasn’t very helpful.
I will keep everyone updated. I hope this is the last part that I need to order online. I’ll try to do a summary video when I’m done because I haven’t found many that really get into this level of detail on repairing this specific issue online. I’m just glad I’m keeping this thing out of the dump and I hope to start using it soon so I can start to build and repair some stuff around the house. Super excited about building a French Cleat system in my shed.
