That's great news. Thanks for the feedback. I believe the only correct FUCA design is one that will accommodate the slight rotation that the arm makes as it travels up and down with the chassis movement. Any other style, and especially trying to lock down bolts, will stress the bearing/bushing assembly and not last too long. Plus, this stress must be hindering the complete movement of the arm as it tries to travel and fight against the resistance. Even the stock arm gets away with the 2 axis movement by letting the rubber bushings twist a bit. But with poly bushings, they just can't handle the strain too long and give up quickly (ala, Z1's bushing style).
