Using CFrame and welds for body armor but it isn't working. Any ideas?

I am trying to put a piece of armor on to the players UpperTorso. So I'm creating a weld between an object that is in the exact center of the players UpperTorso and the armor piece. But I need the armor piece to be a couple of studs forward so that it's on the front of the players torso and not inside of it. I tried using CFrame but I believe I'm doing something wrong.

ArmorChest = game.ServerStorage.ArmorChest
ArmorConnect = game.ServerStorage.ArmorConnect

script.Parent.Touched:Connect(function(hit)
    if hit.Parent:FindFirstChild("Humanoid") and not hit.Parent.UpperTorso:FindFirstChild("ArmorChest") then
        Char = hit.Parent
        ArmorClone = ArmorChest:Clone()
        ArmorClone.Parent = Char.UpperTorso
        ArmorConnectClone = ArmorConnect:Clone()
        ArmorConnectClone.Parent = Char
        ArmorConnectWeld = Instance.new("Weld")
        ArmorChestWeld = Instance.new("Weld")
        ArmorConnectWeld.Parent = Char
        ArmorChestWeld.Parent = Char
        ArmorConnectClone.CFrame = CFrame:ToWorldSpace(Char.UpperTorso.CFrame)
        ArmorConnectWeld.Part0 = Char.UpperTorso
        ArmorConnectWeld.Part1 = Char.ArmorConnect
        ArmorClone.CFrame = (ArmorConnectClone.CFrame + Vector3.new(2,0,0))
        ArmorChestWeld.Part0 = Char.ArmorConnect
        ArmorChestWeld.Part1 = Char.UpperTorso.ArmorChest
    else

    end
end)

It gives the following error, Workspace.EquipButton.Script:15: attempt to call method 'ToWorldSpace' (a nil value)
