My boom has a square-ish metal plate riveted to the bottom of the boom, matching the boom's curvature. In the middle of the plate is a hole with a slot on one end. That's the best I can describe it without a picture.

Does anyone know where I can find the "male" fitting that would attach to my vang so it can connect to the plate on the boom? Anyone know what I'm talking about? I'm assuming the part I need would look something like an enlarged nail head so it could fit into the hole and then slid back to lock it in place.
