I soaked all my hood parts in Evaporust and they're ready to send to Eric. I found that the latch itself still had yellow dichromat finish on the side that was bolted to the hood! The little latch opener was somewhat cad plated in the area where it also bolts to the hood and most interesting is the hook and handle - it appeared to be all cad plated under the bolt mounting holes and again on the underside where it bolts to the hood. The hook showed no sign of yellow dichromate as your is but had some cad playing on the inside of the hook. The handle showed cad playing on the top side where it would not be likely to get handled much. All very interesting that everything on mine was cad plated except for the latch!
