Once again, RPM has heard the cries for help, with the re-release of the RC10 Classic, some users were having compatibility issues with RPM A-Arms. The RC10 Classic A-arms aren’t quite as wide as they used to be so Associated shortened the length of their hinge pins. That means those pins no longer work with RPM A-arms or older versions of the stock RC10 A-arms. To fix the problem, RPM contacted the original manufacturers of the stock Associated hinge pins and they had a new set made to the old specs.
MSRP is $6.95, look for a March 18, 2014 release. They can be found using RPM Part# 70590
