Rear most exhaust hanger bracket

Hi guys anyone any experience of changing the rear exhaust hanger? Mine is very rusty but speaking to Volvo it seems there are a few issues...

I have the bracket made up of a bracket bolted to a plate which is bolted to the chassis looking like this

Attachment 31579

Then with the bracket bolted to it
Attachment 31580

It appears the hanger part is no longer available and so is replaced by this
Attachment 31581

From what I have read this just bolts to the chassis as one unit removing the need for the middle spacer bracket

I was wondering if anyone knew if this affects how high the exhaust is held (what with a middle bracket now missing) and does it fit with the standard mounts and rubbers? I'm pretty sure it isn't compatible with that mid bracket

Thanks!
