Been lookin'-can't find-someone that carries an extensive shank/tap/fitting/washer/attaching nut/hardware selection-I'm assembling my own tap tower and need the shortest shank with the concave outer finial and the convex inner washer(spacer) set up that comes std. in a single tap tower rig.I don't need a faucet or another tower so I'm tryin'to save as much $$ as possible. Lemme know. Thanks,Shane
