I don't have one for sale because its on my C10, but keep an eye out on ebay or craigslist for Storz adapters. They fit 7/8" tubular bars so your options are practically unlimited. Depending on what bar you choose, cable and line lengths may require longer replacments and / or re-routing.
SearchTempest is a great tool for searching ALL of Craigslist and you just might come up with one.
