Here's a Brand new in original packaging Shimano Ultegra ST-6500 Front Cover and Left Name Plate. This is for an earlier Ultegra 65XX shifter, not the later version meant for Shimano ST-6510 (it has a little screw to secure). Shimano discontinued all the models of the 65XX name plates so these are super hard to find, particularly new and in the original packaging.
