Well, others have pointed out that the ST was a short-lived model (swell...). I found one of the sport rack sets:

The guy selling it has no idea whether it'll fit an ST or not. Sadly, I'm no longer in the position to do major alterations on things (at least not metal things). His suggestion was to see if the ST is anywise similar to an RS. (The can-am site is no help with this, btw.)

If not, then not. Thought I'd ask.

Thanks!
