Porterbuilt makes a really nice deal, that comes complete with cross-shafts, bushings, and upper / lower balljoints. Definitely not free but even the cheapest tube a-arms ain't really cheap.

Their arms center the wheels in the wheelwell, I guess this is mostly for looks but might also help with tire clearance if you drive around all aired out all the time. They can also make them shorter or longer than stock, depending on what brakes and hub / rotor combo you're using.
