Chris, I disagree with you about the rigid front axle mounting being a bad thing. The wear that happens to the base around the front axle, is caused by the spring clips that hold the axle in place. There is pretty much no wear on the frame around the rear axles, because they have a rigid mounting, like the Turner front axle. The plastic bush is not chopped out by rotary movement of the front axle, it is chopped out by vertical movement. Get rid of the vertical movement, and you don't need or want a plastic bush. Use a rigid U bracket, and there is no vertical movement. It costs more than a spring clip, but it is way better.
