Thanks Tim and Whitedog for the responses. The pictures of the fenders really tell the story. And I should have remembered that: my first A-D Chevy was a 55-1st, and I had the grille out of it for awhile. The parking lights I think I can deal with. The round vs. square corners are another matter... Since I don't have a truck now, my inquiry is mostly a what-if.
I saw a cool 54 with its original grille without the center bar/nose, and the cross bar cut out. In the grille opening there were 3 narrowed 53-prior bars. Nice affect.
