I cannot find the bracket part number for the AC pump on a 2,2 diesel engine
This applies to Saab with 2,2 diesel engines.
The AC pump bracket is the same as is used for the power steering pump, so it means they share the same bracket. This bracket is not sold separately, it is only supplied with the power steering pump.
