The two small parts maybe;
far left, might be a hold down for the weather strip under the back of the hood on top of the cowl
second from left appears to be a cable hold down, possibly for heater controls or maybe for the choke cable.
Is the paint the right color to have come from the truck?

That is pretty impressive if that is ALL you have left over.
