The wiper blade connection looks to b a different kind of connection than I am used to.The auto is a 2013 SRX and the connection seems really beefy. Will a normal blade fit or is the replacement a Cad part only? The issue is that it will not pivot left or right when in use. It's at least 2 years old and just didn't survive this years Missouri winter. I originated on the N* forum about 10 years ago and the SRX is quite new to me, your knowledge would be greatly accepted. Thanks Ed
