Wow, I had never noticed that Walter had only four fingers on one hand.

I did notice the significant fighting style differences due to my love of the martial arts. The Sentai Black ranger was a rather formal user of what appeared to be a branch of Karate itself, while Zach...well yeah...

As far as Zedd goes, I am relatively certain myself that he has no Sentai counterpart at all. That footage should be all American. That said, they did frequently use the same footage with different voice tracks in those because it is cheaper.
