UPDATE: SOLD, Was on eBay. As I understand it, this top was quietly manufactured for Willys Motors by Koenig, but never branded a Koenig. I am also of the belief that it fits both the CJ-5 and the DJ-3A, though the latter needs the windshield with ‘wings’ to fit.
This brochure makes it clear that the CJ-5 hardtop with sliding doors also provided an option for hinging the door instead. I think Mike might have told that was an option, but I’d never seen documentation of it until now.
