'66 Barracuda Leaking Power Steering Fluid

Well, I've procrastinated enough....I've been putting this Barracuda (273 auto) together for about a year now. It should be ready to drive soon ('soon' being a relative term :)) . I've noticed it is leaking power steering fluid, but I can't tell for sure where the source is. I'm going to clean everything off & try to identify & fix the problem. If it's easy, GREAT! If it's NOT, I may need some advice on how much trouble replacing the pump, etc. is. Does the exhaust manifold need to be removed? As you know, it is a PITA all by itself. Are pumps hard to come by?
I'd rather not do this, but is it possible to simply(?) remove the power steering stuff & steer the car the old-fashioned way?
I've never had a car with power steering before, so this is all new to me.
Advice welcomed!
Thanks.
