Ouch... In that case I have given the wrong year for lots of 1973 models Shall I repair this by hand or is it easy for Antoine to change all [Typ 2 / T2] 1974s into 1973s?
A quick search revealed that only the Westfalia with a specific type of opening roof are listed as 1974 ( which is correct ). The L versions with a side strip along the body ( together with the two-tone paint and the rubber band in the bumper ) are 1974+ models. So, I suppose there's no need to group changes.
