For just the step you could sacrifice a ball by cutting just above the part needed to stabilized the step. Then to tow just change balls without removing the step. If you aren't going to tow you could add a step plate to smooth it out.Thanks - When I posted that your other assembly pictures hadn't posted ? Just the final product - now I see the whole picture of how it works.
Still think it looks great - especially with the hitch painted black also.
