I think if you search this topic you might find the mirrors we all use are not stock to the 53-56. They were made for a later model, maybe 61-66. I think the stock ones had a square head. Hope some one lets us know for sure.

I still believe the chrome round mirrors did not come out until 1957 or even later. I have never seen the round mirrors in any dealer catalog, accessory list and never saw a 53-56 truck in a junk yard with these round chrome mirrors on...
