I know that there is at least two bolt = lengths for this (3 belt) pulley.  When I replaced my '84 1.9L a couple of = years ago the long block I received took a shorter pulley bolt.  Fortunately the VW mech that was installing it noticed this and I spent = a week getting the correct bolt.  He wouldn't use washers for spacers, = said they may interfere with maintaining the correct torque over time = (BS or not, I don't know).  I don't remember how much difference in length = there was but I think it was about 1/2 inch.  I did a little research and = found that in late '85 was when it changed.

a couple of problems I have seen worth pointing out on the = vanagon engines
the bolt for the front pulley locks up before the pulley = is tight I cant explain why this keeps coming up but I have had to chase the = threads in the crank and add washers to get the pulley secure there does not seem = to be more than one bolt length
