Truck sport mirrors

Thankyou moparmarks I am aware van pros sells them but there just WAY too expensive, I just need a clean used set, vntned thanks for the info I cannot seem to get on dodgeconnections site now, it won't load, I'll try again later, I was not aware the mirrors were different do you know the difference? I'm hoping for ones with flatter bases as I am wanting these for my 56 Dodge, I just like the style of these.
