aero wiper conversion

[big jase]

just recently bought some aero wiper's and arm's to fit to my b6 a4 tdi 03 plate. went to fit them today and the driver's side wiper arm hole that goes over the spline on wiper mechanisum is to small ?.

is that write? or have they sent me the wrong part.
the passanger side wiper arm has a bigger hole than the driver side arm and that fits ok ?.

bought the aero conversion of ebay, and the listing was that iw would fit the b6 2001, up to the present b7 ?

dont know if it help's but the part number's on the wrapping for the wiper arm's are 8e2 955 407 c and 4b2 955 425 c.
