Boombox changes orientation on death?

I have this gamepass script that adds a boombox to the players back, and when they have the gamepass they get the boombox perfectly. But whenever the player resets or dies from something the boombox orientation is all wrong on respawn, instead of being on the back slanted at a 45 degree angle, its piercing through the entire body. Help?

local RADIO_REMOTE=Instance.new("RemoteEvent", game:GetService("ReplicatedStorage"))
RADIO_REMOTE.Name="BoomboxEvent"
local MarketplaceService=game:GetService("MarketplaceService")

game:GetService("Players").PlayerAdded:Connect(function(plr)
	plr.CharacterAdded:Connect(function(char)
		if MarketplaceService:UserOwnsGamePassAsync(plr.UserId, 5068130) then
			if char~=nil then
				local torso=char:FindFirstChild("Torso")
				if torso~=nil then
					local boombox=game:GetService("Lighting").GamepassBoombox:Clone()
					boombox.Parent=torso
					boombox.Position=Vector3.new(torso.Position.X-.7,torso.Position.Y,torso.Position.Z)
					boombox.Orientation=Vector3.new(0, 90, 45)
					local Constraint=Instance.new("WeldConstraint",torso)
					Constraint.Part0=boombox
					Constraint.Part1=torso
				end
			end
		else
			if char~=nil then
				local torso=char:FindFirstChild("Torso")
				if torso~=nil then
					local boombox=game:GetService("Lighting").Boombox:Clone()
					boombox.Parent=torso
					boombox.Position=Vector3.new(torso.Position.X-.7,torso.Position.Y,torso.Position.Z)
					boombox.Orientation=Vector3.new(0, 90, 45)
					local Constraint=Instance.new("WeldConstraint",torso)
					Constraint.Part0=boombox
					Constraint.Part1=torso
				end
			end
		end
	end)
end)
