I had the same prob with the two tanks(on my 05 Ridgeback)....unfortunately i didnt realize until i had the new tank painted for my 05.......damnit! Think i may knock off the rear mounts on the frame, tap the frame and use the newer tank. I think i can fab a set of tabs that can mount where the original tabs were using the new tapped hole. that way i can use both tanks. gotta look into this a little more, but seems possible from what i remember. figured that the dealer would have ordered the correct tank to begin with...... f&^%$*
