UPDATE: This post has been merged and reworked after I figured out that the two tops were actually related.
In July of 1963, Fresno-based Automotive Fiberglass Company placed an advertisement in Four Wheeler magazine for its new fiberglass hardtop. I wonder if the builder of this top was also a member of the Fresno Jeep Club?
This is the 1963 ad:
July 1963 Ad from Automotive Fiberglass
This Automotive Fiberglass top appeared on a CJ-5 for sale in Fresno in 2010. It is the only jeep I’ve seen with an Automotive Fiberglass Top:

TIMELINE —
July 1963: Automotive Fiberglass places ad in Four Wheeler Magazine;
November 1963: Top King Manufacturing files design patent for an altered version of the Automotive Fiberglass top;
February 1964: Top King top is advertised in the Four Wheeler Magazine;
September 1964: A more detailed ad is placed in Four Wheeler Magazine.
A few months after the Automotive Fiberglass advertisement, two design patents were filed and assigned to Top King Manufacturing. You’ll note that the rear side-angle has been reversed. The mid-section insert piece for the side was also changed, altered from a triangle shape to a rhombus shape. Here’s the design patent information from the Official Gazette of the United States Patent Office:
November 1963 Design Patent filing for Top King. Note that I haven’t had the time to investigate the designers mentioned in the patent.
By February 1964, King Top was advertising the newly redesigned top in Four Wheeler Magazine. Curiously, the company listed its name as the Top King Fiberglass Company rather than Top King Manufacturing (could be a relic from the Automotive Fiberglass company days):

Seven months later, this second ad was placed in the September 1964 issue of Four Wheeler Magazine. The company had corrected its name for the ad back to Top King Manufacturing. Additionally, Top King announced it would soon have flatfender versions of the top available, along with a half cab version. Have any of these survived?
