Quick question for you guys. I want to swap out the brash bushings in my Grizzly X3 with some ball bearing units. does anyone know if someone makes a kit, or what the dimensions on the bushings are so that i can find a replacement? I would just measure them myself, but I am out of town at a Tool Show and was hoping to pick some up while I am here so that I can be ready to go when i get home. Thanks a lot
