Im fairly sure i paid just short of £40,
I often wonder as loads of people replace these and the centre one, if they replace the other two on the backboxes at the same time. Theres 5 hangers all in
5 on a 182 and iirc 3 on a 172
^^Not really, they can snap if you have an aftermarket exhaust, or wear down and cause the exhaust to knock of the rear beam.
So the knocking isn't gonna damage anything?
Cheers
