My '67 Impala, 283, has the power steering pump loosing fluid. I think it is coming from the upper hose in the back of the pump. I want to tighten the clamp for the hose. Well, the bracket to hold the pump on is just above the hose clamp. Any recommendations on how to get at the screw for the clamp on that hose? I assume someone here has encountered this problem.

Thanks
