Jim,
I am convinced that it is a '46 because of the Plate on the firewall (altho' admitting I have made so many other mistakes). My door is not rust free and had planned to do sheet metal work on it's bottom where the major rust exists. I don't care about being 100% original (don't tell anybody that I am not a purist or they might kick me out of this garage). What do you think would trump the plate with VIN numbers that check out with all the various sources I have managed to dredge up? One other thing it has is the stainless steel molding that I thought was peculiar to the '46 grille, you know, those pieces which sort of shield the top of the vertical bars associated with the lower grille? In a previous forum I read where the earlier years didn't have them in stainless. I can't swear they are stainless but they are the only part of the grille which isn't rusted out.
thanks for your words of wisdom ....
Lane
