I Have A Set Of Rail Extensions To Go From 121 To 136 Plus The Hyfax Extensions Also. For A 2003 Rx 1 Should Fit Many Yamahas. They Came In A Kit But Were Not Used Because My Customer Went And Bought Another Set Before These Showed Up And Didnt Tell Me. Have Never Been Put On And Have All The Fastners With Them. Need 125 Out Of Them And Will Ship Free.
