Spreader connection to Spreader Bracket

Thread starter #1
My buddy and I flipped my boat last weekend (he was at the helm). In the process, the starboard side spreader came detached from the bracket attached to main.

What sort of pin is it that connects the spreader to the spreader bracket and where can I find one? Is it it a rivet or grommet of some kind? I could pull the boat from the buoy and drop the mast to look at the other side, but am trying to save an extra step.
