I believe 51 was the last year for 5.5. bolt pattern. 52 was same as small Ford car starting in 1949. The Wizzard
yes 49-53 ford cars all had the 5x4.5 bolt pattern. Mercury 49-51 were 5x5.5 and 52-53 merc were the small pattern. tok
The widths vary on the 5x4.5 wheels also. Front of wheel will look the same but the width can be about 1/2 wider on some. Probably wagons and Mercurys. Eddie
