This is very interesting. In 1984 I bought a '49 3100 deluxe cab, and when I looked at the engine block, it had a "48" stamped in the block. No big deal. When I got tune up parts at NAPA, they were wrong. So I got the distributor number, and the parts guy said that they were for a '48. Maybe it was an early '49??
Long gone now, what a great truck that I used and enjoyed for ten years!
