All the VOs I have I've used the crimp on bracket at the rear and the L bracket on the front. Something is wrong here. Did you say you bought these second hand?
What bracket is being used at the front? Where are you based? I've mounted enough I could give some help.
Actually did use it once on my cross check, but found it easier to flip on and off with the L bracket. All depends on the gap between mounting points and the tire. I've become pretty handy at bending the crimp bracket to bridge decent sized gaps.
