This is just my two cents worth, but unless your building a 100 point show car, or have a true "surviver" car that's never been touched, I'd recommend that you paint, or powder coat ALL of your front suspension and steering parts, as leaving them bare metal will leave the parts open to rust and corrosion. Eastwood makes some very nice paint products such as "Chassis Black", "Aluma-blast" and many other similar products that will give your parts a factory look without leaving them without any protection from the elements. ;)
On my 66 Coronet, I had almost all of my front suspension and steering parts, along with my K-member powder coated back in 2001 or so and it still looks like new today and the parts are MUCH easier to keep clean! :yes: If I remember correctly, it ran me between $200.00 and $300.00 back then to do all of the powder coating.
