In the book it shows the holes for the bolt that will go through bushes on the axle bracket for the rear supension to be 11/16 inches dia. Why? Isn't the bush internal dia 3/8"? Shouldn't the holes be the same diameter? Am I missing something?

Bear in mind the book's full of errors so I suspect this is just another one.

Note that the rear axle bracket hole spacing is different too- the spacing needs to be the same or the axle won't lift or drop under bump!

HTH,
