Trust me - I ended up with a heap of parts that I purchased over the winter for a 1947 GMC pickup (i.e., 47-49) and nearly none of the fit. So now I just order 46 parts and haven't had an issue yet. So I have come to refer to her as a 46.
Being that she is date-stamped as a January 1947, all the parts were made in 46 - so I makes that much more sense for me.
