GM part is an original 1969 Pontiac Firebird Trans Am power steering pitman arm for the close ratio box of 2.5 to 1 lock to lock - for V8 motors. Part number is 7806616 - which is the hardest to find part because it's for a close ratio power steering box. How do I know this to be true? Because I pulled it off my own personal car back in the 80's. This part has not only been in cold storage for over 20 years, but also has been sitting in a California dry environment pretty much all its life. In English, its the best that they come. I have personally inspected this part for wear, which is nominal if any and bead blasted to a finished piece as of December 29th, 2012. This is as real as it gets and this particular part is extremely hard to get a hold of.
