Q: Can you tell me the difference between 11-08354 and 11-08365? Other than the minor price difference, all that I can think of is the extra mounting hardware - but why would it cost less for more hardware?

They have different terminals. It just depends on how your buss bar is set up, as to which one you would pick.
