The Sanden (called "Sankyo" at that time) compressor was used briefly in '78 and may have snuck its way into a few '79 and later vehicles, but most of these cars used the Nippondenso C171, a different (and cheaper, and not as good, though not awful) round-body compressor. Brackets and mounting are not the same between the Sanden and the Nippondenso.
