LA Intake with Serpentine Setup

Cut the whole ac pad off. Then just route the belt around the idler and across to the power steering pump. That is essentially what the non ac bracket is but the idler pulley rides about an inch higher. Been done plenty of times.
This depends on the power steering bracket used.

A full size truck power steering bracket mounts the pump higher, so the non AC belt and routing works. However, some have reported a stock A-body battery location hits the pump.

A van power steering bracket clears the battery setup, but now the belt will not clear the water pump pulley.
