« on: March 01, 2010, 10:21:47 PM »
Does anybody know GM oil pump casting numbers. I am looking for the casting number for this  oil pump 3964255, but the person i charge says i need casting number for him to find this pump in the inventory. Any help is greatly appreciated. Or does this oil pump have the number cast into it.
