There are 3 or 4 versions, with a single balance pipe facing forward just below the carb flange, with two balance pipes coming out sideways just above the mating face with the head, and with or without a take-off for the vacuum retard on the dizzy. The version with twin pipes is '71MY on, so you may not have them in the US. AFAIK, there are no other differences in length, diameter, whatever, so if the manifolds have the right combination of pipes, you should be in business. The cast numbers may be the last number of the part number. Maybe someone with a parts book can shed some light on this? ------------------------------------------------------------------- Unsubscribe? mailto:type3-request@vwtype3.org, Subject: unsubscribe
