This is a Saginaw GM power steering pump for Chevelle‘s, Camaros, GTO, nova, Firebirds, etc. this pump is never been installed and is in new condition. The pump also comes with the Pitman arm. If you look these two up on national parts depot Chevelle you’ll see the total cost is 630 something dollars without tax and shipping. I believe the pump is 10 to 1 fast ratio and 2.6 steering lock the lock.
