No, any Tbird rear rim uses the same hub setup. Some of the difference's are the amount of spokes on some. I used a TBird standard rim from a 2002. It had the same amount of spokes(32). You can also use the rear wheel hub from an adventurer as well. One thing about Triumph is they always try to use as much from their parts stock instead of creating new pieces and configurations. Hope this helps.
