This should be an easy one, but on my '67 small block with power steering (no a/c), I loosened the one bolt on the power steering pump (within the slide area) which I thought would allow me to push the pump toward the center of the engine (so that I could remove the belt), but it will only budge a small amount. Still too much tension to remove the belt. Any other bolts that need to be removed or loosened. Thanks.
