How to make characters spawn in old ROBLOX morph?

I am trying to make an FPS and need the players to spawn in the normal morph that say a guest would spawn with. I know games like Call of Robloxia have this and what he has is kinda what I want. I know how to script and edit scripts, just not a pro. Is there any like parts that I would need to consider.

game:GetService('Players').PlayerAdded:connect(function(player)
    player.CharacterAdded:connect(function(character)
        local s = character:FindFirstChild("Shirt")
        local p = character:FindFirstChild("Pants")
        s:Destroy()
        p:Destroy()
        local shirt = Instance.new("Shirt", character)
        local pants = Instance.new("Pants", character)
        shirt = "shirt template linkie link" --Shirt AssetId
        pants = "pants template linkie link" --Pants AssetId
    end)
end)

This is just something I found in free models, but this changes you shirt and pants, where as I need the morphs, so I'm guesssing not too much needs to be changed here.
