Yep, just remove the air con pump, gives you a bit more room! For the PAS I'm using a MK3 VR6 pump with the 24V pulley attached. I wanted to use the 24V pump as it was newer put my pipes didn't match up.
Yep! You only need a different bracket on the MK5 engine as it had electric PAS (i.e. nowhere to bolt a MK3/4 PAS pump). In this scenario it would be best to fit the bracket from the early 2.8 PAS equipped engine.
