Alan, VW did away with the flange because in some cases the timing belt
would wear the edge off and the resulting jagged edge quickly destroyed
the belt. All replacements and everything since (including TDIs) use the
flat pulley with no edge flange, this works perfectly. In the past I
have machined the flanged pulleys down to duplicate the later style. So,
the pulley you are getting will be just fine, better in fact than what
you had there originally.
