I forgot to mention that some stores may also stock the 3/16" x 51" pre-made piece in Nickel Copper tubing, which if available at your local store, is what I'd get today instead of the plastic coated steel that I linked above. Either will work but the nickel copper is a little easier to bend and in the long term, more corrosion resistant, though the plastic coated steel linked above will probably outlast the rest of the vehicle anyway.
