I haven't added bushings in anything for a while, but I did it frequently years back and will again when it comes up. The last time I mentioned this on list, I was unable to make the point that it wasn't a torque thing, but that the bushing just added support and improved the feel, as Will said. Better luck this time, hopefully. Ron N
