i ordered a set of those mirrors for my 61. You can flip the bracket around at the base of the mirror and then spin the arm. I sent them back because they looked dumb on my truck and for the life of me I could not make them so I could see behind me easily. They were so hard to aim that I finally took them off and sent them back. I exchanged them for the standard issue driver door mirror. I was disappointed because i had dreams of them looking really cool, but no dice. They look and work a lot better on the 67-72 trucks, my buddy has some. I think that they were designed with that truck in mind, not my 61. Oh well the stock mirror is good enough
