I need to replace the headlight Wiper Blades on my 2000 XC70 Got a set from IPD great price quick shipping, they also sent me the OEM Volvo Blades there is a drawing on the box and it appears that they just pull off and clip on the new ones? any tips or tricks? I searched the forum couldn't find anything! I don't want to break or bend the arms or anything as they work perfect. I just replaced the windshield and rear wipers! Thanks for the help! Bill
