The timing belt pulley needs to be the AHU part, but I believe the balancer and the rest of the pulleys will bolt up fine.  The accessory brackets will be the trouble spot I believe.

You can run the mk1 accessories including pulleys on the AHU. Power steering is the only thing that would require some mods to work.
