The Magnum PS pump needs to be tweaked a little bit to work with the LA PS pump brackets. In this photo, you can see the second stud (circled, Magnum - clean - pump) that has already been installed and was robbed from the LA PS pump. The Mag originally comes with a thin-head bolt (circled, LA pump), since none of the mounting points on the Magnum pump bracket are on the back of the pump.



Note: there seems to be something funky about the bolts between the two pumps. Pretty sure that the Mag pump has metric fasteners. However, the stud from the LA pump threads in just fine on the Mag pump, but the bolt from the Mag pump doesn't seem to want to go in to the LA pump. Strange, but it works the way I want it to...
