I got my pillion exchange from Aussie Biker today. You send them your stock Triumph pillion, they build a new longer, higher and wider one on the same frame and return it to you ASAP. Mine got to Noosaville, Australia April 24th and it showed up at my home on May 1st.
Pretty fast turn around and the workmanship is excellent. Can't wait to let my gal give it her blessing. If anyone's interested in seeing how it looks, drop me an email and I'll send a photo your way.
