so I broke an a arm this weekend, no biggie right. So I bought a new set and wow, wtf. The arms that came with my WC were nicely made. smooth and did not require tooling to make them free. These replacement arms are well, crap. Sharp molding all over the place. I filed and dremeled them and they still are not free. if I lift the arm with the tire and shock off, and release...it stays up. I will keep removing material until its free, but what happened? Did AE get a new molding company?
