The point that is being missed here is that a 2005 Dakota tread width is much wider than the earlier Dakotas. I have a 55 setting on an 89 Chassis and with proper wheel selection up front everything will work out. Measure twice cut once!! Take your tape and check the original 55 width against the 2005 and earlier width, My own opinion is the earlier chassis are lighter and easier to fit the early cabs to. You can also buy dropped spindles for them! Joe
