RE: Which Bilsteins?
Bilstein only lists one set of shocks for the Vanagon: *

*I ordered mine from Van Cafe and they only list one grade also.  Their
stock numbers match the numbers on the Bilstein site.  They are rated HD
(Heavy Duty) by Bilstein and their description fits the performance I've
encountered.  So far a great shock on the highway but take rough roads great
also while maintaining a very 'sure footed' feel and performance for my
Westy.
So I guess I have the 'Heavy Duty' and don't know what the 'Touring' are.
