Hi to you Paul, I dont think the Scout car are the same, but if its any help the shims fit on the big square caps which bolt over the bearings, with more shims in, the cap can not be bolted down so much so the bearing is looser, by taking out shims and or swapping for thinner ones you can obtain the correct pre-load on the hubs, NOTE you MUST fit and remove or put in the same number and thickness on the top and the bottom so as to keep the hub in a central position in relation to the axle.
