I found on youtube what looks like all the episodes of both shows.

Route 66 ran fron 1960-1964 and had 116 episodes (50 minute long episodes)

Naked City ran from 1958-1963  and had  138 Episodes    (22 minute long episodes) 

It was just as much fun looking at the cars,clothing and life in the late 50's and early 60's as watching the story.

A lot of famous actors made their acting start on these shows. A real nice enjoyable flashback  to watch.
