Unity C# coding for game application

I have a Unity game project in mind. I have used asset packages to make a demo. I used the Polyperfect low poly war pack and the Polyperfect Ultimate crafting package and merged them together (see clip). The problem is The item tossed from the inventory of the Crafting system does not behave like a War pack pickup. I have identified the component that needs changing. If put the Pickup_Ammobox_7mm into the ToSpawn GameObject of the Item Game Object Creator. I get the effect I am chasing. I need to change the To Spawn Game Object depending on what is in the ItemClump_Tossed. I dont know how to do this? Can you Help? (see Picture)
