Q's about door profile and mirrors

[randyjohn]

currently i have big 4-leg camper mirrors on my truck and i want to put a set of "dumbo" mirrors on. going to the yard soon and need to know what year and model vehicle (i.e. burb, blazer, van, etc.) fit the contour of a 74 door? did the door shape change at all between 1/2 to 3/4 ton. i've heard the van mirrors have a tighter armature. the problem is i can't fit the truck through my garage door without turning my mirrors in. thanx for the help.
