1932 Cabriolet rumble hinge bolts

[Lincolnville]

I'm trying to figure out if I'm missing a part for the rumble hinge for a 1932 Ford Cabriolet. The bolt hole for the half of the hinge that attaches to the body is 5/8" - painted black. The corresponding hole on the hinge that attaches to the rumble lid is 1/2". The bolt itself has a shoulder, so it fits nicely in the 1/2" hole. The threads are 3/8". Am I missing a sleeve that goes over the bolt where the hinge pivots? Otherwise, the rumble lid would seem to rattle around. All parts are original to the car.
