I noticed many pre-1963 Chrysler 300 cars on the site do not have their letters in the titles. I thought this should be an easy fix as long as the right info is presented.

From Wikepedia (please verify)
1955 C (C represented "coupe" not all 300s were "C")
1956 B
1957 C
1958 D
1959 E
1960 F
1961 G
1962 H
