does anyone know what you need for an automatic to manual hub conversion on an 1985 pickup? so far i have the two aisin hubs, two spindle nut kits and because of my axle didn’t have a snap ring on the end i have to get two of them i’m assuming? Are the snap ring called the front axle inner snap ring or the birfield snap ring because marlin crawler has both of them but i think i only need one.
