Delphi 670 12.7:1 power steering gearbox with GM type II power steering pump and extra reservoir.
Everything was purchased new by me from Unisteer years ago as a matched setup. Has 1,000-2,000 miles from new as it was all on a rarely driven car.
I really have no idea what this stuff is bringing now. So, feel free to make me an offer.
$400 obo, plus shipping.
