Welcome to Dr. Björn's Auto!
Here are some of the parts for a sliding door mechanism of an early T3 Vanagon (80-85) which are often difficult to find.
In the drawing (click on it to see details) you can see numbered parts for the individual items in the mechanisms. The numbers in the drawing correspond with the prefix numbers of individual parts in the item list below.
There are some model overlaps and you may want to compare with the later model mechanism to ensure that you get the right part. Call or email us if you cannot find the part you need.
