After the long discussion on this problem a while back, BB offered to replace any of the defective bushings. I requested one and then placed a pen kit order and requested a replacement set on that order. When I received the order, BB put a note in the order that the replacement Sierra bushings would be sent as soon as he received the corrected bushings. I have not received them yet, that was about a week ago. I am holding off turning any of the sierra kits until the corrected bushings are furnished. I hope that will be soon
