Wheel spacers?  Doesn't sound factory to me, as the true weight capacity
of the axle is decreased with such devices.  Sounds like either the
front or rear axle has been swapped, because the lug pattern would have
matched from the factory without using any spacer/adaptor.
Rear axles being more common than front driving axles for that era truck,
I would expect the rear axle isn't the original, so what is there may not be
the RA-20 listed on the lineset.
