FPS arms moving with view

I would rather not make artificial arms as most FPS do, but I would like to alter to C0 and C1 of the Left and Right Shoulder Motor6Ds. I found a script for this in the toolbox, but it only worked for R6. I need a script for R15. Here’s the code of the R6 script for you to take a look at it if wanted:

local player = game.Players.LocalPlayer
local character = player.Character
if not character or not character.Parent then
	character = player.CharacterAdded:wait()
local torso = character:WaitForChild("Torso")
local rightShoulder = torso:WaitForChild("Right Shoulder")
local leftShoulder = torso:WaitForChild("Left Shoulder")
local camera = game.Workspace.CurrentCamera

updateSpeed = 0.5/2

while true do
	character["Right Arm"].LocalTransparencyModifier = character["Right Arm"].Transparency
	character["Left Arm"].LocalTransparencyModifier = character["Left Arm"].Transparency
	local distance = (character.Head.Position - camera.CoordinateFrame.p).magnitude
	if distance <= 1 then
		rightShoulder.C0 = rightShoulder.C0:lerp((camera.CoordinateFrame * CFrame.new(1, -1, 0)):toObjectSpace(torso.CFrame):inverse() * CFrame.Angles(0, math.pi/2, 0), updateSpeed)
		leftShoulder.C0 = leftShoulder.C0:lerp((camera.CoordinateFrame * CFrame.new(-1, -1, 0)):toObjectSpace(torso.CFrame):inverse() * CFrame.Angles(0, -math.pi/2, 0), updateSpeed)
		rightShoulder.C0 = rightShoulder.C0:lerp(CFrame.new(1, 0.5, 0) * CFrame.Angles(0, math.pi/2, 0),updateSpeed)
		leftShoulder.C0 = leftShoulder.C0:lerp(CFrame.new(-1, 0.5, 0) * CFrame.Angles(0, -math.pi/2, 0),updateSpeed)
