I got my original manual steering box out today ans eas getting ready to drop the power steering box in. I noticed the manual pittman arm had a hole in the end that was connected to the center link. The power steering box I have already had a pittman arm on it but it has the stud with the grease fitting on the end that connects to the center link. Obviously I can't connect the pittman arm that I have. Now I am wondering if my steering box will even work? When I bought it I was told it was out of a Chevelle. Anybody have any part numbers for power steering boxes for '66?

thanks.

Just figured out I have a GM 800 series box #5691676. Unfortunately it is not the quick ratio one.
