In my quest to tart up the bike (Bagster just bought fits like a glove, thanks to those who assisted with info), I need a RennTec rack. Now, I've been offered a rack with the following code REN7234B (for a 2000 Mille). The partnumber for the actual Tuono rack is REN7273B; different partnumbers as you will agree. I could of course ask renntec, but fear that they will look at their wallet, besides, the auction may end before I get an answer. So, if anyone knows if they are interchangeable, please let me know asap. Thanks, Jere....eeer.. Spete
