I am trying to identify the GM pump in the next 2 pictures. It has a smooth case at the back to allow for it to pivot in the 235 6 cylinder bracket. I do not have this pump, just pictures I have been forwarded.
This is the pump that I need.




I have found that the pump in the next picture is more common, however it has an extra bump above the rear pivot point that will interfere with the bracket. If you recognize the pump in the first two pictures with the smooth case and maybe have one, If you could forward me the casting number I will try and find a remanufactured one. Thank you in advance.
