I have a 78 bahner with a 12 JC pump. Stock pump with new Place Diverter. Wanting a bigger roost. Whats my opions or whats the trick. Do i Change the bowl and you a drop snoot and a wedge or a rooster booster? Or is there another way without breaking down the pump? I am very mechanical minded and can handle taking it apart but just want to know what to expect or would it be a mistake to break it down without rebuilding and what awould i need?
