Hi,i am looking for the number off the axle on my k85. i have opened the 2 wheel caps but can only find a number on the locking nut. the spreader in 2007, would anyone know where the number would be? i need to get 2 slack adjusters, 21 spline and approx 40mm diameter. Dealer is extremely pricey so i wanted to get from bpw agent if possible. thanks
