I have not been able to install rubber bushing in the lower colum. I tried inserting the bushing after the box had been assembled without any success. I also aligned tabs and using a deep socket have been unable to drive in rubber bushing. I also removed the steering shaft, inserted the bushing and then inserted steering shaft which pushed the bushing out the colum. The tabs are not the problem. Could the problem be that these are old and have lost their resiliency? My Triumph never fails to present me with new challenges!!!!!
