I've notice that the parts you bought is Hyundai parts. The picture from the link in China is Kia parts. The part no. is the same though. I've search the internet, the part number belong to Hyundai not Kia. It is for Hyundai Azera GLS.
A NazaKia agent check the Kia online spares and there is no indication that the absorber mounting has been replace with a new one.
Does this mean the mounting is from Hyundai, does it fit our Rondo, if so than we can search for Hyundai parts here. Online price for the parts is about US65.00.
