UPDATE: The September 1962 issue of Four Wheeler included a full page ad for its new hardtop and half-top designs. The magazine included both a full-page ad and a short article. Given this info, it looks like the top redesign was introduced during the summer of 1962.
=============================
Originally Published July 7, 2020: Sometime in the early 1960s, Kelly Manufacturing altered the design of its angular full and half hardtops. The new tops eliminated some of the horizontal bevels and the flat back design for a slightly more elegant design; but, the tops did retain the angled top-side that was so recognizable (As I don’t have much knowledge on any interior changes, this post will stick to the major exterior differences) (See Kelly’s connection to Beck and Kemco and an early Kelly brochure) (Also see CJ-3B page Beck and Kelly histories)
Interestingly enough, Kelly branded the Flatfender tops as 23-series, but not the CJ-5 tops. Here’s a 1962 Kelly brochure that highlights a wide variety of the rear-angled design for both the CJ-5 and the flatfenders, along with the model numbers:

To make the differences more clear, let’s take a look at the early Kelly design (these early hardtops were also marketed by the Berg’s as JeepKing hardtops). Notice the horizontal bevels along the driver’s side rear and on the rear latch. Also note the flat vertical back of the hardtop.
