Thanks Nick. That is exactly what I was looking for, I don"t have the stop, and now I think I can make one for my hitch. As we talked in the past, my lifting bars are from a VAO, which give me 3 holes at the back to attach the lifting arms to. It allows me to have about 3 1/2" difference in height when raising or lowering the hitch. This was more information than I hoped for, will post you back when I get it all made.
