The re-release of the RC10 Classic has come with a few changes that affect users of RPM RC10 Rear A-arms (RPM #70542). RC10 Classic A-arms aren't quite as wide as they used to be, so Associated shortened the length of their hinge pins (Associated #6380). That means those pins no longer work with RPM A-arms or older versions of the stock RC10 A-arms.
To rectify that problem, RPM contacted the original manufacturers of the stock Associated hinge pins and had a new set made to the old specifications. These new hinge pins are now available through RPM.
