I believe I may have an NOS set of mirror heads (could be aftermarket though).
Can someone tell me what size the heads are and let me know if there is a way

You probably noticed the dimensions (7.5" X 10'5") in Killer Bee's post 11.
The appearance of original heads differs significantly from all aftermarket heads I've seen. The first picture below is of an original head from a '72. I've seen heads like this on trucks made through at least the early 90s by the big 3 manufacturers. They were almost identical with only 3 very subtle differences I've detected. If interested, I will look at my collection of heads in several days and try to get some pictures that show these differences. The second picture is of a head currently on my truck which I believe to be post 1972. You will notice the embossed emblem, the most obvious difference, at the bottom which I don't think appeared on mirrors before 1973. On this mirror, I'm also using a stainless elbow that has a horizontal leg about 1-1/4" shorter than one used on these trucks.
Incidentally, as long as the stainless is not dented, they'll buff to look better than new. No need for NOS in my opinion.
