Are you guys sure about the part numbers that fit the X5. Going to the Summit Racing Equipment website it has the 424A which fit the X5 (though they only spec to 2004), but the 422A they say is for the X3, while the 422B they spec for the X5.

Also they have the 418A and 418B, but both are listed as front blades and not spec'd for the X5.

What gives?
