Power Steering Pump on A 74 Slant 6

Hello Mopar fans, I've been gone for minute
Have a quick question, I need to replace my power steering pump on my 74 Scamp /6. Now I can get one either at O'reilys or Autozone but was wondering do I need to replace anything else while switching pumps? Also what brand would you recommend for the swap? My old pump been leaking for awhile and I am tried of seeing spots on my garage floor.

Thanks
Van Leer
