These then got pushed into the tips and fitted to the car. I will have to post up a final shot later as one of the old brackets on the tips snapped when I went a bit OTT with tightening with the impact driver so I am waiting for stainless clamp in the post but one side fitteded nicely. The rings I made tightened down fine and still gave the adjustment in angle because of the profile I had achieved by grinding down the sides.
