? I'm trying to move a player's arms to the camera in R6

I'm trying to make a script that changes Properties in MOTOR6D, with the player's arms so that they move to the position of his camera, something like this: https://ctrlv.cz/jiKK in R6

BTW: Im not using fake arms! Phlease help :(

my script was:

local player = game.Players.LocalPlayer
local cam = game.Workspace.CurrentCamera
local m6D1 = player.Character:WaitForChild("Torso")["Left Shoulder"]
local m6D2 = player.Character:WaitForChild("Torso")["Right Shoulder"]

while wait() do
	m6D1.CFrame = cam.CFrame + Vector3.new(0,0,1)
	m6D2.CFrame = cam.CFrame + Vector3.new(0,0,-1)
end
