The outer window scrapers on Type 34s are (of course) unique to the model and have been obsolete for many years. With minor alterations Beetle Cabriolet window scrapers (1965–79) are a perfect replacement. They are about 1 inch longer than Type 34 scrapers and just need to be shortened at the forward edge. Installation of these seals requires removal of the vent frame and door windows to gain access to the five screws used to hold the scraper in place.
Most VW parts suppliers carry (or can order) these window scrapers. The part numbers are 151 837 475D (left) and 151 837 476D (right).
