AU$460!They are ripping you off!
Did you have the oem plastic moulding?I have the Rbs and kept the originals.I just had a look at both plastic mouldings and it may be possible to adapt/modify your oem to fit!Suggest you take the oem moulding to paintshop to see if they can adapt it!
If you dont have the oem moulding, I am sure some of our members can let you have one for free!
