Since Cannons come equipt from the factory with nerf bar mounts heres a tip that will save you some frustration. When you take the frame plugs out to install your nerfs I suggest coating the end of the nerf or the hole with anti sieze. I had a heck of a time removing one of my nerfs for servicing.because the end galled in the frame hole making it very hard to remove. I have AC nerfs and they look great and seem very strong at a good price.
