Metro GTi Steering arm part numbers

I'm in the process of rebuilding the rear of my GTM K3, for those that don't know it uses two front subframes from the K series Metro so I essentially have two sets of front suspension.



I need to buy new lower suspension joints and I understand I need to match these to the steering arms as the castor was different between the normal metro/R100 and the GTi.



The steering arms on the rear have the part numbers RUG10008 and RUG10009, would I be right in believing these are the GTi arms?
