Whats an Good Brick Weld Script for Cars?

Okay, I have this Car Where all the bricks fall off the front.. I used this Persons Weld scripts but it does not seem to Keep the bricks welded on. I have the script in the Brick Itself. Any Ideas?

function weld()
	local parts,last = {}
	local function scan(parent)
		for _,v in pairs(parent:GetChildren()) do
			if (v:IsA("BasePart")) then
				if (last) then
					local w = Instance.new("Weld")
					w.Name = ("%s_Weld"):format(v.Name)
					w.Part0,w.Part1 = last,v
					w.C0 = last.CFrame:inverse()
					w.C1 = v.CFrame:inverse()
					w.Parent = last
				end
				last = v
				table.insert(parts,v)
			end
			scan(v)
		end
	end
	scan(script.Parent)
	for _,v in pairs(parts) do
		v.Anchored = false
	end
end

weld()
script:Remove()

This is really long...

t = script.Parent
wait(5)

function stick(x, y)
	weld = Instance.new("Weld") 
	weld.Part0 = x
	weld.Part1 = y
	local HitPos = x.Position
	local CJ = CFrame.new(HitPos) 
	local C0 = x.CFrame:inverse() *CJ 
	local C1 = y.CFrame:inverse() * CJ 
	weld.C0 = C0 
	weld.C1 = C1 
	weld.Parent = x
end

function Weldnow()
	c = t:children()
	for n = 1, #c do
		if (c[n].className == "Part") then
			if (c[n].Name ~= "MainPart") then
				stick(c[n], t.MainPart)
				wait()
				c[n].Anchored = false
			end
		end
	end
	end
	if (c[n].className == "Flag") then
			if (c[n].Name ~= "MainPart") then
				stick(c[n], t.MainPart)
				wait()
				c[n].Anchored = false
			end

                 	if (c[n].className == "Handle") then
			if (c[n].Name ~= "MainPart") then
				stick(c[n], t.MainPart)
				wait()
				c[n].Anchored = false
			end

 	if (c[n].className == "Hat") then
			if (c[n].Name ~= "MainPart") then
				stick(c[n], t.MainPart)
				wait()
				c[n].Anchored = false
			end
		end
		if (c[n].className == "Seat") then
			if (c[n].Name ~= "MainPart") then
				stick(c[n], t.MainPart)
				wait()
				c[n].Anchored = false
			end
		end
		if (c[n].className == "SpawnLocation") then
			if (c[n].Name ~= "MainPart") then
				stick(c[n], t.MainPart)
				wait()
				c[n].Anchored = false
			end
		end
		if (c[n].className == "TrussPart") then
			if (c[n].Name ~= "MainPart") then
				stick(c[n], t.MainPart)
				wait()
				c[n].Anchored = false
			end
		end
		if (c[n].className == "VehicleSeat") then
			if (c[n].Name ~= "MainPart") then
				stick(c[n], t.MainPart)
				wait()
				c[n].Anchored = false
			end
		end
	end
end
