Starting August 1979 -- factory aircon installation with new compressor type. It is a very nicely designed unit, however the interior cooler protrudes into the passenger legroom and precludes using a package tray.

Overview

From August 1979 a uniform kit was offered with DKKC (Diesel Kiki) radial-type compressor.

This kit is beautiful and easy to install. Unfortunately the interior cooler unit is bulky and protrudes farther into the passenger legroom than other types.
