FWIW, MU is selling reproductions (SMS? I seem to recall) for around $84 with all hangars, bolts and clamps, available for 2" and 2 1/4" (but you could use your own clamps for any other size).
That might have been then, but this is now (and they are selling correct ones now).I believe I looked at those and they were correct for the mustang and not the cougar? I think the cougar hangers are different right vs. left.
