I had an hour or 2 filing all the castings inside the pump, and also the mounting holes for the cone and reverse bracket arent drilled deep enough!
This needs serious revision! The mounting holes for the cone are NOT drilled deep enough! The stock one is drilled clear through and the hardware protrudes through the back a little, this one is not drilled all the way! Castings are shotty and I needed to file for about an hour or so to make it work.
