Easiest way for me was to buy the Kubota dual rear remote kit for $320. Came with the valve, pipes, mounting hardware, levers, female quick connects. Probably cost you most of that to put a kit together yourself. They make a kit for the current non TLD BX versions, so they might have one for your 2230. The kit is sold as whole goods, so you have to go through sales, not parts. Try calling a dealer to see.
