A rough summary S-class chassis: 116 - 1973-1980 126 - 1981-1991 140 - 1992-1999(?) 220 - 2000- 126 chassis diesels include 300SD - 1981-1985 300SDL - 1986-1987 350SDL - 1990-1991 350SD - 1991 (source: http://home.hiwaay.net/~gbf/mbmodels.html) > The 126 chassis is longer and heavier than the 123.

No vacuum at all? In my 123, vaccum physically moves the vent flaps but that is the limit of vacuum involvement. Everything else is electronic. -john
