Matching Torsion Bars, Leaf Springs and Shock Absorbers

I know these are probably rarer than hens teeth, especially now 40+ yrs afterwards, but I have used the 76 fleet/police factory optional rear sway bar for a-bodies. I highly recommend it. It's not crazy thick, but it just works. I'm sure there are aftermarket sway bars out there, but I can't personally vouch for any of them. Whereas, the factory bar is simple yet elegant and I know it works great on my 66 cuda.
