Hey Puzzigully. I've got the same setup as you and had the same fouling of the belt on the alternator pulley (actually the alternator shaft). To resolve, i inserted 2 x washers between the compressor mounts and the brackets and it moved it forward just enough for the belt to clear the alternator shaft/pulley. It also lined the A/C belt up more square.

See pic below where the 2 x washers are visible.

Hope it helps
