Baby fake torso not welding to real torso?

Hi.

I'm trying to copy off an old baby morph script (don't judge me). I did it, but for some reason, the fake torso is not welding to the real torso (I think).

Can someone please tell me what I missed?

My script:

storage = game:GetService("ReplicatedStorage")

storage.Events.PlayerToBaby.OnServerEvent:connect(function(player)
	print("Request received.")
	local char = player.Character -- Get character
	-- Head mesh size
	local mesh = char.Head:FindFirstChild("Mesh")
	if mesh then
		mesh.Scale = Vector3.new(1, 1, 1)
	end
	-- Torso management
	local torso = char.Torso
	torso.Transparency = 1
	torso.CanCollide = false
	-- Existing FakeTorso destruction
	local fakeTorso = char:FindFirstChild("FakeTorso")
	if fakeTorso then
		fakeTorso:Destroy()
	end
	-- New FakeTorso
	local body = Instance.new("Part", char)
	body.BrickColor = BrickColor.new(1)
	body.Position = torso.Position
	body.Name = "FakeTorso"
	body.FormFactor = Enum.FormFactor.Symmetric
	body.Size = Vector3.new(1, 1, 1)
	-- Welds
	local weld1 = Instance.new("Weld", torso)
	weld1.Part0 = weld1.Parent
	weld1.Part1 = char.Head
	weld1.C1 = CFrame.new(0, 0.25, 0)
	local weld2 = Instance.new("Weld", torso)
	weld2.Part0 = weld1.Parent
	weld2.Part1 = char.Head
	weld2.C1 = CFrame.new(0, -0.8, 0)
	-- FakeTorso mesh
	local bodyMesh = Instance.new("SpecialMesh", body)
	bodyMesh.Scale = Vector3.new(1.2, 1.5, 1.2)
	-- Remove legs and make arms invisible (so the baby can hold tools)
	for _, each in ipairs(char:GetChildren()) do
		if each:IsA("BasePart") and each.Size == Vector3.new(1,2,1) then
			if each.Name == "Right Leg" then
				each:Destroy()
			elseif each.Name == "Left Leg" then
				each:Destroy()
			else
				each.Transparency = 1
			end
		end
	end
	-- Notification for debugging purposes
	print(player.Name.." has been successfully babified.")
end)

Old baby script:

debounce=false

function onTouched(hit)
	if hit.Parent ~= nil then
		if (hit.Parent:findFirstChild("Humanoid") == nil) then return end
		if (hit.Parent:findFirstChild("IsaMorph") ~= nil) then return end
		local human = hit.Parent:findFirstChild("Humanoid") 
		local player = game.Players:GetPlayerFromCharacter(hit.Parent)
		local char = human.Parent
		if (human ~= nil) and debounce == false then
			debounce = true
			if char:findFirstChild("Infant") == nil then
				local mesh = char.Head:findFirstChild("Mesh") 
				mesh.Scale = Vector3.new(1, 1, 1) 
				local torso = char.Torso
				torso.Transparency = 1
				torso.CanCollide = false
				if char:findFirstChild("FakeTorso") ~= nil then
					char:findFirstChild("FakeTorso"):remove()
				end
				local body = Instance.new("Part")
				body.BrickColor = BrickColor.new(1)
				body.Parent = char
				body.Position = torso.Position
				body.Name = "FakeTorso"
				body.formFactor = "Symmetric"
				body.Size = Vector3.new(1,1,1)

				local w1 = Instance.new("Weld")
				w1.Parent = torso
				w1.Part0 = w1.Parent
				w1.Part1 = body
				w1.C1 = CFrame.new(0, 0.25, 0)
				local w2 = Instance.new("Weld")
				w2.Parent = torso
				w2.Part0 = w1.Parent
				w2.Part1 = char.Head
				w2.C1 = CFrame.new(0, -0.8, 0)
				local bodymesh = Instance.new("SpecialMesh")
				bodymesh.Scale = Vector3.new(1.2, 1.5, 1.2)
				bodymesh.Parent = body
				local rightleg = char:findFirstChild("Right Leg")
				if rightleg~= nil then
					rightleg:remove()
				end
				local leftleg = char:findFirstChild("Left Leg")
				if leftleg ~= nil then
					leftleg:remove()
				end
				local marker = Instance.new("StringValue")
				marker.Parent = char
				marker.Name = "IsaMorph"
				characterparts = char:getChildren() 
				for i=1,#characterparts do 
					if characterparts[i].className == "Part" then 
						characterparts[i].Locked = false
					end 
					if characterparts[i].className == "Hat" then 
						characterparts[i].Handle.Locked = false
					end 
				end 
			end
		end
		debounce = false
	end
	print ("scriptcomplete")
end

script.Parent.Touched:connect(onTouched)

R15 does not have a torso, use UpperTorso
