Intermediate Pulley for all Diesel Vanagon

This is an aftermarket Intermediate Pulley for all Diesel Vanagon.  This is 29mm wide and it is made as a copy of the original one.  It says 068115021A on the box and on a sticker on the inside of the box, but on the part itself it says 068115021D so I assume it is the same part just known under a couple of different numbers.
