Go to a junkyard, and pick one up.
You can also use one from a B13, 90-94, it's white, and aluminum. BE SURE TO KEEP THE BOLTS, AS THEY ARE SHORTER/LONGER THAN THE PLASTIC COZVER(dont remember if its shorter or longer, i just remember that part.) Just make sure to buy a new B13 gasket.
I pick them up for around $15-40, depending how much of an ass the guys are.
