Powerflex Bushes

[KitsonRis]

Car had the MoT test last week and there were two advisoraries for bushes being worn. I want to get this sorted as there is also a knocking noise from the front and it could be related to this.

The items are:

* "Anti-roll bar rubber bush deteriorated but not resulting in excessive movement (both sides front)"

* "Trailing arm rubber bush deteriorated but not resulting in excessive movement (both rear axle bushes)"

I have a quote from the garage to do this and supply parts, mainly as I hate doing bushes! But thought about fitting Powerflex ones instead. Looked on their website and a bit confused to what ones and want some clarification before I buy them.

I am going to guess it is item 3 and 5 that I need in their diagram. But there appears to be two options for each bush. The rear ones are two sizes - 72.5mm (PFR85-415) and 69.0mm (PFR85-610). The front ones on their cataloge don't state sizes (PFF85-411-21 or PFF85-411-23). Does anyone know which ones I will need?
