All Chrysler Corporation parts are even-right and odd-left in 1973. This holds true for car and truck parts. Not sure when they started it though. Judging by the parts books I have, they began this arrangement around 1961, with it being firmly entrenched by 1964. It also holds for Studebaker parts, by the way, at least during the 1960's.
