Yes, this looks like the same drawing, but without any installation 
tolerances in the dimensions.

The Bentley gives a dimension of 4.5-5.5 mm, which would permit some 
amount of impossible overlap. 5 mm might be okay, but the seal I 
measured seems to be 5+ mm wide. OTOH, the dimension given for the 
upper needle bearing allows for a minimum of 1 mm of clearance, which 
gives some tolerance for assembly variation and seems perfectly 
reasonable.

There are VW special tools for installing these parts. Does your 
collection of tool drawings include VW273C (Type 3 lower) and VW273D 
(Type 3 upper)? If so, those would contain the correct dimensions.
