Karl,
My only consolation regarding the 1954 grill is that the GMC grills of that era were even more questionable in their beauty.
The appeal of my truck was its cost in 1971, $200. My $70 1948 panel was closer to rusting away. If you can't be with the one you want, want the one you're with (or, something like that).
If your 41 sedan has a stovebolt engine in it, in my mind you are a stovebolter, in a purer sense of that term. Just be ready to take the jabs from the truckers.
