nope, They(chrysler) never made that color tint. it looks purple"ish which means it's most likely an applied window tint film that has been cleaned with Windex and discolored. Nowadays a good glass rear original is a bit hard to find but not exactly "rare". For the glass rear windows you can have 2 colors, clear and a green tint. A/C cars came standard with tint, non a/c came with clear but had an option to use tinted there should be a stencil on the glass part . look for A or M51 clear,A or M52 fdor the tinted light green one.(it's iron in the glass that makes it green).... 69 year could also be a thinner A or M series 61 or 2.
