The Chrysler 300 (Chrysler 300 Non-Letter Series) was a full-size automobile produced by Chrysler from 1962 until 1971. It was the replacement for the 1961 Chrysler Windsor, which itself filled the place in Chrysler's line previously occupied by the Saratoga just the year before that (1960).
It was slotted below the letter series, adding 4-door versions and ran along letter series until its discontinuation in 1966, becoming the sole 300 model until 1971, when production ended.
1969 was first year for "fuselage styling", there were two engine options; 440 and 440 TNT.
